Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

I love sabremetrics, OPR/DPR, +/-, and stats in general. I was excited for these OPR+ and DPR+ numbers. But unfortunately, just from looking at them, I can tell we might have taken it a step too far and they might have become less accurate.
The fact that my former team, 116 is ranked 3rd at the event should be the first indicator (as well as the ranks of 45, 365, and 234 being so low), despite struggling to score the entire regional. I don't have the raw OPR numbers handy (on my Mac), so I can't give detailed comparisons between the rankings, but judging by these, I think it may have become less accurate to what the team's real performance was.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

I have similar concerns. Last night I ran every regional that we had numbers for. I had hoped to create a combined "top 25" list from every regional, until I saw which teams rose to the top, and which teams did not. I did a double check on TBA to see how these teams had actually performed, and was surprised that teams in some regionals - such as WI, NYC, and Oregon - were showing up on the top despite the fact that many had only moderate records, and did not appear to be high scorers. Some regionals, the numbers corresponded with what I expected, but other regionals, the numbers did not. The one factor that I'm still not sure about, and perhaps you can help me with this Sean - the team scores are not only the robot - so the purpose of this equation was designed to look at not only how effective the robot is, but also how well the HP does, too.

During DC, I had my scouts do extensive scouting on each match, looking at how many MRs each scored, and how many MRs were scored on them (developing a match by match +/-). What I failed to do, was to have them track the HP and how many SCs the team delivered to the HP, both of which had profound impact on the game. If I just looked at the performance of each robot, 45, 365, and 234 were on the top of my list. But I knew from observations that 2199's HP was deadly, and 118 had the ability to get at least 2 SCs exchanged. So I wonder if there isn't some aspect of the OPR+ calculation relying on those other factors, and not just how effective the robot is.

I'm going to run these numbers (looking at all three factors - robot, HP and SCs) while we are in the midst of the competition at Chesapeake this weekend to see if I see any trends. Perhaps this equation isn't going to give us the info we are looking for, but I still want to run some additional numbers to see how they do.

Best regards,

Steve

It was perfect because we were #1 after Friday. And therefore it must have been the best tool ever. Just Kidding, however, it really did help in our meeting. It confirmed that KRUNCH was as amazing as we thought.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

The numbers you are referring to, are the OPR/DPR numbers. The numbers that we are talking about are the OPR+/DPR+ numbers - which, yes, I know don't look a lot different! :)

I pulled the data from FL, and ran the calculation for the finals, using the OPR+ and DPR+ numbers. Here are the results ...
First, averaging the score across all three finals matches, the avg Red score was 74 and the avg Blue score was 84.
I plugged the calculated values into the OPR+ and DPR+ formulas, and here is the outcome Red 68, Blue 90. An 8% difference for Red and a 7% difference for Blue between the predicted values and actual values. Penalties, which are not considered in the calculations, could easily account for that kind of discrepancy.

In doing so, one thing became obvious, the OPR+ number can not be taken into consideration by itself, but must be linked with the DPR+ number - but not simply by adding them together - but in the separate calculations of Red vs Blue Score. I'm going to do some additional modelling of the data to see how we can get a combined ranking value.

I am going to run additional calculations at other regionals and see how they correspond.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Hi, I've been trying to access the ratings for the Dallas regional, and the program has not been able to parse the html data. Does anyone know why?

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Annoyingly, it looks like the HTML output by the Texas regional is quite different than that spat out by every other regional so far. It has the same style as the HTML printed out by the first 1-2 weeks of regionals last year. It might be time to adjust OPRNet to read off of TBA instead of USFirst.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Well, as long as you get the TBA feed version perfected by next Wednesday, you have my permission to do it. :p

Seriously now, if a TBA version is more reliable, then go for it. With the latest copy of your code AND a TBA version, I feel very confident we will be able to gather some fairly valid information. It will be interesting to compare the results.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

i was wondering, i used to use OPR's back in 2006 and 2007 when they first became available

I was curious as to how the opponents you play factor into the situation. i'd much rather see a formula like a RPI or a SoS used alongside the OPR, DPR, and PM systems already established

ie

RPI
=
teams winning percentage x .25 +
opponents winning percentage x .5 +
opponents opponents winning percentage x .25

SoS
=
(Opponents win percentage) - (Your Alliance Partners win percentage)

i think looking at these stats alongside the OPR, DPR and PM systems can truly show which teams are better than what is shown on the standings, and which teams just got bad luck and got paired with their worst nightmare's

(Im using this to scout because i don't have any video from the Oregon Regional to view.)

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

V8: Now uses TBA as a fallback for 2009 regionals, and as the only source for pre-2009 regionals. Note that because of this, this version should be able to do any regional that TBA has in its database, which is a big improvement over earlier versions.

...It may have a lot of bugs in it. I think I got rid of most of them, but there are probably a few left.

I will try to implement this, I don't think it should be too hard so long as I get the recursion right.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

V9: Now computes RPI. I looked at SoS, couldn't find any quick explanations for it, so I didn't bother.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

the win percentage of whoever your opponents played during the regional

yeah, i saw that five minutes after i posted that.

Oh, SoS-Strength of Schedule, pretty much, what was your opponents record. but i guess that's already factored into the RPI as is

i love it when we can use a formula for College Basketball and FIRST at the same time

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

From the command line:
"oprnet (regional) (year) (statistic) (team/rank ranking) q > output.out"
Ex: "oprnet il 2009 all r q > output.txt" will print all stats for Midwest 2009 to output.txt in a tab-separated table.

That will spit out all the data to a file called output.out (it can be called anything). It'll all be tab-separated (make sure you put that q there, or it won't put the tabs), so you can copy/paste it into excel. Look through the thread for examples of the usage.

WP: wins / games played
OWP: Average of a team's opponent's WP's
OOWP: Average of a team's opponent's OWP's

This recursive implementation is very slow, but it was very easy to implement.

There is no Match Zero....

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

That's not the problem. That is just an error in how I report which match it failed on (it should have a +1 on it). My best guess is that TBA changed how its HTML is created, and now my parser doesn't work anymore.

Edit: And my suspicion is correct: they've greatly changed the HTML. However, it'll be easier to parse now, so it shouldn't take too long to make a new parser.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Yea, my TBA parser broke a couple of weeks ago because of this...didn't even think about it since the match 0 thing threw me off. I had to add a bit of protection from those match 0's...

In my latest version I have a flag set which writes a formatted line out to a java file. If I run the main program from Eclipse, it will download all of the data and auto-program itself into the next time the program launches. Fun stuff ... or scary iRobot stuff, however you look at it :ahh:

I will say that doing the permanent data increases the program size by a few hundred K, but if you're using Java a few hundred K shouldn't matter :p

That's because I added the text for that feature, but didn't finish adding the feature. I suppose I'll do it now. v11 coming soon (if it turns out to be easy).

Still can't get old regionals.
This is the tail of `oprnet.exe ny 2008 all`
Also, instead of putting in the search all, maybe it would just be better to run it on your own and post the results, so we don't harass first's bandwidth too much (or have to wait for it to process)

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Alright folks, the feature that my PM box has been filling up for:
V11
-Can now do every single regional at once
-Fixed a bug where it would lock up trying to parse some regionals

Example syntax:
Will print all statistics for all regionals to allRegionals.txt. On my computer, it took about 1 minute to finish. If it takes longer than 5, something is wrong-ish. You'll still be able to open the file, but it might not have every team in it.

Now that everything can be spat into a single file and analyzed in excel, I've realized:
1) RPI is still broken (look at the 'gt' regional's RPIs)
2) SAA is fairly useless so far as predicting a team's finishing position
3) OPR is fairly good at predicting a team's finishing position
4) I need to do some more parsing to get more statistics. How does OPR correlate to win %? What is the distribution of OPRs among elimination alliances?

You make a good point about harrassing bandwidth. Here is a nice tab-separated data block:

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Awesome job! This is a very cool and very powerful program. When used in conjunction with more detailed scouting reports this program could be very useful.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Bongle, i understand how you show all results into command prompt.
However, the CP window automatically closes right after it outputs the results. Also, when i type: "oprnet all 2009 all r q > allRegionals.txt" it does not do anything but show all results, followed by immediately closing itself.
What is the problem here? Am i doing something wrong or missing out on some step?

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

hey this is really an awesome program. i have three questions.

1) if it's not much of a problem, you think you could incorporate a way to search for stats of specific teams by just entering their team number?
2) you think there is away to average a certain team's over all stats from all of the regionals they have participated in
3) will there be a way to use this program for championships?

awesome work and if its a hassel to any of those, don't stress. lol

thanks

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

It ought to not show the results, but instead write them to the file called allRegionals.txt in the same folder as OPRNet. Are you actually typing quotes, or is that added just for the post?

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

oh...and one more thing...i think, if you could, try to rank all the teams in every regional based on the stats to see which team is the best out of everyone. it would help majorly in a lot of debates. lol

just another idea

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Bongle, great work!

Pretty much repeating what everyone else has suggested, but with a methodology attached in case they're unclear :P
Can you load all the matches into one matrix and solve OPR/RPI from there?

By the way, before the all regional option got in there, I dumped them one by one and threw them into a spreadsheet, then did some other analysis by hand.
http://www.chiefdelphi.com/forums/sh...t=76194&page=7
Interesting statistical points about the top 25 OPR:
Only 12 went on from setting that high OPR to win that regional.
Also, team 71's 63.55 OPR at the Midwest regional stands out beyond the rest, but their performance (which probably did involve quite a lot of scoring) didn't seem to add up to that. This is just an easy example of the inaccuracy possible in this analysis.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

The amount of programming needed to implement these features isn't that much, but the reason the stats all end up as tab-separated is so that you can copy-paste into excel, and sort by any parameter you want.

Currently, the divisions are available as 'regionals'. You just need to type cur, arc, new, or gal to output that data.

Try launching it from the actual command prompt (start->run->cmd), or try making a .bat file in the same directory, putting "oprnet all 2009 all r q > allregionals.txt" in it, then launching that. All the data should end up in a text file call allRegionals.txt. Of course, it is kind of redundant: all the regional data is available in my post.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

I had my brother write a very similar program before I knew this one existed, one way we tested our results was by using the stats we calculated to predict what the results of matches would be.

In our program offensive score had some predictive power but defense had no relation to reality.

Did you find differently when you tested your results?

This is great, thanks for putting the time in to making this thing work! One general recommendation, could you have a column on the left that always has the numbers 1-X(however many teams there are) so you know where each team ranks? Looks great though, hopefully this application can be adapted to next years game fairly quickly!

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Bump: Thanks to FIRST not updating the format of the online results this year, I just want to point out that OPRNet (and I'm assuming the other implementations) work in 2010 as well.

Notable rankings:
1114 [Pittsburgh]: 6.8
63 [Pittsburgh]: 3.7
217 [Cass Tech]: 4.9
469 [Cass Tech]: 2.4 (this seems low, but it is probably because 469 is dependent on good alliance partners supplying it with balls, so it quals they probably end up with lower effectiveness)

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Fantastic!!

I was about to dig out your code to see if it would work this year as well. We used it last year with excellent results.
Now that we know it works, you can count on us using it again this year. All we have to do is wait until week 5.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

It worked last weekend when i was using it at the Florida regional. The only part that bugs me is the "predict" section. you have to predict the seeding score by yourself because it still does it in WLT format.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

I love this program, our team has done something similar to this.

It tells you everything you really need to know and you don't need the extra stuff.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

I can take a look at fixing it, but I misplaced the source code (and didn't attach anything beyond v6), so the best I can do is work from v6, unless there are people I PMed source code to post-v6.

It needs updating anyway, because the regional list won't work with new or name-changed regionals.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting

As requested.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

I didn't really look at the code. I know it requires .NET to run after helping install it on scouting laptops last year and figured that was why it was named OprNET. I do most programming in my Linux boot and I still havent installed Visual Studio Express like my old laptop (which I used to work with the Bongle's old '08 OPR code among other things). I'm glad that team update 16 made OPR relevant again (though it is still not a great fit for the game)

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

It should just require the MSVC runtimes (I think, I'm not good at this redistributing thing), which I imagine are included in the .NET distributable. Probably won't help with your linux needs though, since it uses the Win32 WinINet functions rather than an OSS standard.

I called it OPRNet because it was (inter)net-capable, rather than having the user manually create text files to parse.

OK, that explains the name. Installing .NET is probably a simple solution for people having trouble running OPRNet (particularly on old XP laptops).

Also, I dont want/need a Linux version, the Windows version is great. Thanks Bongle! I have a dual boot machine and the Windows boot is what I use at competitions anyway to run Windriver, Excel and save my battery. Windows is the right choice since all of the KOP software is Windows.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Did the OPR miss the mark for the Florida Regional? The alliance of 1251 + 1612 + 86 won the whole shebang with a combined OPR of 5.4 versus alliances with group OPRs of 9.9, 9.2, 7.1, 6.4, 5.6, 5.2, and 5.10. If OPR were a good predictor wouldn't the team of 1592 + 179 + 3164 be a virtual lock with a group OPR of 9.9? In the past OPR usually was a good indicator of the strongest alliance in the elimination rounds. In the Quarterfinals, the top three teams by group OPR were knocked off.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Great observation.
You need to understand, OPR is just one tool to help you decide. I'll bet in qualifications, 1251, 1612 and 86 were not able to compete along side teams that would compliment their game strategies or abilities. Look at it as a perfect storm. When you bring three teams together that fully complimented each others abilities and were able to play as a single unit, their performance as an alliance would be way better than they were able to show individually during qualifications.
This is why raw numbers is not always your best predictor. Observation and paying attention to all input is a scout's best approach. Leaning on one detail, like OPR, can be mis-leading.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Another reason OPR might be a poor elimination predictor is because the rules essentially change in eliminations.

In qualifying, it isn't really in anyone's interest for teams to play heavy-handed defense. In eliminations, defense is a key factor. So teams with a pneumatic-tire 8-motor, rocket-powered 8WD suddenly are much more useful, while teams with highly mobile feather-light (and light on grip, like mechanum/omni) robots suddenly find it much harder to score.

A perfect example is 469: they have a low OPR (well... compared to their reputation) because they are only at maximum effectiveness when they're playing with highly effective robots that can get their ball loop going. In qualifying, that might not happen often. An ball-supplier bot is limited in offensive power by its home-zone teammate that is trying to get balls in the net. 469 is a defense-proof near-perfect ball supplier. When defense ramps up and solid ball-deliverers become available, suddenly 469 is an unstoppable force.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

At the Oregon, New Jersey, and Pittsburgh regionals, the alliances with the best OPR were the winners. Over the years, it has been consistant that the OPR team score was a 90%ile indicator of sucess. Bongle makes a great point about the defense as the 1251+1612+86 alliance was the number 2 rated defense in the eliminations. I am curious about how many of the regional winning teams were predicted by OPR for weeks 1 & 2 in 2010. At a glance, Florida seems the exception.:confused:

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Also, OPR cannot take into account teams that are playing the "seeding points game" by scoring goals for their opponents. There are several very high performing teams I know of that have abysmal OPRs for this reason - because 2 or 3 times a match they were scoring for the other alliance. That's a huge hit to your OPR, SAA and ultimately your PM.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

I think you need to take a look at all four stats to determine who the best robot is on the field.

High OPR + Unusually High SAA + mediocre PM + Strong RPI = a really good robot
High OPR + Low SAA + strong PM + Strong RPI = Good Robot

thats how i look at the stats.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

I have not used RPI in the past since it has such a narrow range of data like 0.16 to 0.40. Obviously higher is better as an indicator of strength of schedule and wins. However its relationship to OPR, DPR, & PM is not easy to compare since these valus are often 20 times larger

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

I noticed this weekend that this is the year of the prediction feature. Running it for KC, the self-check indicates it would have been 70% correct after only 39 matches, and consistently 80% correct after 48 matches. For Lunacy it does much worse. This seems to indicate that this game is much more predictable, and that good robots in one match will often do well in subsequent matches. Note that this is only for predicting the winner. So although it is better at predicting the winner of a match than last year, that's a less useful thing to do than it was last year.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Man this code is awful.

Anyway, v12 (based on v7) is now ready. The prediction feature now has awareness of the new seeding system, though since it can't know penalties, the predicted seeding scores are too high. Even if I gave it an entire regional of match scores with no prediction, the rankings it would give out would still be incorrect because teams would not be getting as many points as they should.

awesome! 1592 top 100! just wondering, what is the Net Rank mean? To me it would factor multiple regionals and somehow be averaged together, however there are different Net Ranks for the same team.

also, i'm curious to see how many of these teams either are not going to championships or are currently on the wait list.

unfortunately the Bionic Tigers, the last i heard, still are wait listed.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

"Net Rank" I think is a bug. If you delete that and shift the rest of the headings over, they all match.

Edit: Nevermind, I just don't know what it is supposed to be.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

by looking at the table, it's pretty easy to see net rank is the ranking of each teams net category.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Bongle, what are the chances you could put this into a web app, hosted on a free server like google apps? That way we could get to it from our mobile devices, web browsers at work (many companies use proxies that prevent this .exe from working), and public computers that have paranoid IT infrastructure.

Given that my expertise is in C++, the chances of me personally doing it are very slim. The best I could do would be a java applet embedded in a web page.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

This is probably a stupid question. :)

If we do >results.csv when we enter a query, where does this text document get saved? I can't seem to find it.

Thanks!

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

It should save it to whichever folder you run the command in. However, I wouldn't recommend writing it to a csv file, the output is not comma separated. You can save it to a txt file. I recommend piping it to the clipboard "| clip" then pasting it to excel. It is nice to have one sheet with all the regional. That is how I generated the Top 30.

Would you be willing to share the v13 source?

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

The v12 source is earlier in the thread, and I think v13 just updated some regional names.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

How do I get the results to output to a .txt? I tried enterring ">output.csv" and ">output.txt" after the results displayed in the command window, but the command window just closed and I couldn't find the output file. How do I get the results to output to something that I could put into an excel file?

Thanks!

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Are you running it from the command line, or double clicking the icon and running from there? I couldn't get the results to store after clicking the icon, but running it from the command line I could. So I just put oprnet on the desktop, opened the command line, type "cd desktop" hit enter, then "oprnet nh 2011 opr t q | clip" and I end up with the opr results by team on the clipboard. Then just paste it into an excel document.

Hope that helps!

For any Mac users out there I have updated my OPR program.

Is it just me or does the predict function not work for the 2011 season?

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

v13 is for last year with the different point based ranking scheme. That doesn't work on this year W L T.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Thanks a bunch, Ian! It's working very well now! :-) For being an FRC/scouting/strategy/excel person, I'm not particularly good with any "programming" but C++ and Robolab!

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

I found that it was crashing for me, too. I'll have to check the source to fix it (and get it to do WLT again)

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Is it just me, or is the Chesapeake regional data not working at all.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Looks like they used the old software to generate the scores page, so it is a slightly different format than OPRNet expects and so it fails to load it. If it gets loaded to TBA (and TBA still uses the format OPRNet expects), then it might be loadable later.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

This is what I got last night when it was working on MD (not working now)

Congrats your team (836) is the "Qualification Match MVP". Chesapeake is an interesting case study. A very clear top tier of 4 formed on the OPR, then was broken up by seeding and Alliance selections (all 4 had 2 or more losses). 1218 had 3 losses, 1 to 836, 1 to 340. 365 beat 340 but lost to 836. 836 seeded highest (4th) followed by 340 (5th), 365 (6th), 1218 (10th). They were then picked in this order with these results
1. 365 (decline AC5 QF)
2. 836 (accept A1 F)
3. 340 (decline AC4 SF)
4. 1218 (accept A2 W)
All the alliances that lost to an alliance that contained another of the 4. When there are no powerhouse alliances and heavy D, anything can happen :ahh:

Thank you Bryan. It was a pleasure working with you this weekend

V14 - Now parses the "fat" style of regional results, a la www.frclinks.com/e/m/il

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

The next chance we will have to use this is at Nationals in St. Louis. What "regional" code would be used for the different fields?

An old executable I have (from 2009) also had the all option to calculate stats for all regionals. That was nice.

Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting
 

Since it ignores elim matches, there is no reason for it to look at Einstein. I also miss the 'all' option.
