Re: Week 4 OPR - All regionals and districts
 

Just wondering what happened to statistics for 987?

Re: Week 4 OPR - All regionals and districts
 

I only posted stats for the week 4 events. Check out the week 3 thread for the LA results.

Re: Week 4 OPR - All regionals and districts
 

Ahhh, gotcha...long day = slow brain:o

Re: Week 4 OPR - All regionals and districts
 

Thanks for this.

Re: Week 4 OPR - All regionals and districts
 

Do you have the total OPR for all weeks yet?

Re: Week 4 OPR - All regionals and districts
 

Don't want to brag but, we're doing awesome. Good job guys!

From 1983

Re: Week 4 OPR - All regionals and districts
 

Great job, Suckworks, er, um...Skunkworks!

[Disclaimer - this is an inside joke that anyone who watches popular online rankings shows knows about, including the team :) ]

Re: Week 4 OPR - All regionals and districts
 

Haha, thanks!

Re: Week 4 OPR - All regionals and districts
 

Ahhhh yea 1629 GaCo 8th in week 4 opr. First time we ever made it into top 8 opr. FEAR THE GECKO!!!

Re: Week 4 OPR - All regionals and districts
 

BAHAHAHAHAHA!

But seriously

:( Sorry 1983, you guys clearly, do not suck. I fear I will never live this down

Re: Week 4 OPR - All regionals and districts
 

Bongle,

Where did you get the data for Hawaii? The reason I have not posted this week is I was waiting for them to post the Hawaii regional standing. Without the total HP, BP, TP and CP, how did you calculate the OPR of those for Hawaii?

I am posting Week 4 OPR without Hawaii at http://www.chiefdelphi.com/media/papers/2174. The World Ranking has also been updated. The standings for Hawaii is missing so I cannot calculate the OPR for that event. When it is posted, I will post another file like last week.

Re: Week 4 OPR - All regionals and districts
 

Just wondering what happened to us on the hybrid and teleop scores? 1056 hit 17/17 in hybrid for 10 points and I'm sure a few partners threw something in. We also only missed one shot (dunk) the entire tournament. You have us at 12th on the OPR but missing on the others. 28 points sounds about right for what we were putting in per match. Sorry we didn't qualify for worlds so we could show our dunker and wheelie bridge dropper. Should have listened to my partner, sorry Maui High, in that first match of semi's. Although Hawaii has the lowest average OPR, I think the top five could go up against anyone. Aloha

Re: Week 4 OPR - All regionals and districts
 

It appears that for the Hawaii regional, only the overall OPR is posted, probably because of the lack of available information that Ed is referencing.

Re: Week 4 OPR - All regionals and districts
 

Please see the attached Excel spreadsheet for weeks 1 through 4 OPR. (Excluding Hawaii)
It has filters to rank by hybrid, bridge, teleop. and total. (Excluding Hawaii, even for the 'total')
It includes multiple entries for teams that have competed at more than one regional.
Feel free to change it up and add any functionalities. (i.e sort by regional, etc.)

Once again, thanks to Bongle for his work on OPR over the years to make it very easy to use and comprehend.

Re: Week 4 OPR - All regionals and districts
 

Interesting things show up in the spreadsheet you posted because teams have multiple entries. It's a bit easier to see consistency (although to be in the top 100 I limited it to, you're pretty consistent already if you made it there twice). These teams show up more than once (I know this isn't perfect because there are some awesome teams out there that haven't competed twice yet):

• 67 claims the top two spots.
• 341 claims THREE spots in the top 10 (4,6,9)
• 2056 claims two spots in the top 10 (3,7)
  
• #: Rankings
• 16: 38 and 42
• 48: 28 and 43
• 148: 73 and 75
• 340: 45 and 59
• 365: 11 and 82
• 399: 44 and 57
• 469: 19 and 39
• 488: 29 and 72
• 610: 30 and 93
• 967: 66 and 95
• 1114: 14 and 22
• 1208: 87 and 88
• 1218: 40 and 41
• 1477: 25 and 63
• 1507: 12 and 17
• 1629: 24 and 79
• 1714: 53 and 70
• 1983: 5 and 16
• 1986: 13 and 36
• 2169: 27 and 56
• 2474: 10 and 46
• 2826: 52 and 74

Together, these 25 teams account for 51 spots in the top 100.

Re: Week 4 OPR - All regionals and districts
 

6 of the top 30 OPR performances of the season have been produced by Canadian teams.

All but one of those Canadian teams has qualified for STL, with only 3161 being on the outside looking in.

3161 was also the team which had a chance to snatch the #1 seed away from 1114 in their last match at Waterloo. They held the tiebreaker over 1114 with a higher Hybrid Points total.

This is the match where it all happened, and also contains a "triple double" with all 6 robots balanced...

Re: Week 4 OPR - All regionals and districts
 

this makes no sense to me at all.....

my team only shot 1 ball at the competition and it missed so why are we in the top half of all of these lists??????

Re: Week 4 OPR - All regionals and districts
 

Here is the average rank of each of those 25 teams, sorted. Take note of the important fact that these are just some numbers, and probably will not be a good predictor of all that much. Except maybe which team has a better average OPR rank out of teams with two spots in the top 100 as of Week 4, it'll help a lot for that. :D

Re: Week 4 OPR - All regionals and districts
 

Suits me! You just helped me make my Top 25 list - promote the teams that have won 2+ events, then 1 win + finalists, lather rinse repeat. Fill in the top performing single-competition teams, bump 2826 up because I saw how awesome they were in Wisconsin elims and I know this OPR stuff doesn't measure those performances, and finis.

Re: Week 4 OPR - All regionals and districts
 

The only issue with using the average OPR is that is disregards changes made between competitions and leads to an inacurate ranking. I think ranking the OPR's from teams leatest event is a more accurate way to rank teams via OPR because it represents what teams are doing currently not in week 1 or 2. An example of this is 365, in week 2 at chestnut hill district they had an OPR of 21.2 ranking 82nd over all while week 4 at Lenape with a new shooter 365 had an OPR of 31.1 ranking 11th or using teams latest event's OPR ranking 7th.

Re: Week 4 OPR - All regionals and districts
 

Because of the way that OPR works your score won't be exactly what it was. Although it's scary to think that you guys' OPR might actually be devalued... not to rub salt in the wound, but I think you might be the best bot in the world that isn't going to STL.

It was great playing with you and against you in Hawaii and we hope to see you next year!

Re: Week 4 OPR - All regionals and districts
 

I think your math is a little off. It is literally impossible to go 17/17 in hybrid and only get 10 points...

Re: Week 4 OPR - All regionals and districts
 

Thanks, we'll take that title. That should generate some funding for next year?

Re: Week 4 OPR - All regionals and districts
 

10 points (2 two pointers) in all 17 matches I think is what is meant.

Re: Week 4 OPR - All regionals and districts
 

Pretty sure Lavapicker means each hybrid period they scored 10 pts...

Re: Week 4 OPR - All regionals and districts
 

Yep, we drove up to the bumper in hybrid, lifted our arm pneumatically and used belts to spit out two balls into the middle goal 17/17 times. Only missed one shot the entire tournament which has to be close to a record too. Our whirling fingers of elastic tubing we extended to collect balls made us pretty effective at collecting balls too. We used pneumatics to wheelie up and over the bridge to drop it too. Very nice design that worked all tournament but alas, we'll not be at worlds to show it off. Even Lebron and Koby don't win it every year which gives us some solice.

Re: Week 4 OPR - All regionals and districts
 

This is definitely a limitation of OPR. I am not sure how valid it is to compare OPRs across events at all, for that matter. I am a much bigger fan of CCWM (OPR+DPR), since it better reflects contributions to score DIFFERENTIAL rather than raw score itself. Many top teams leave a lot of potential points on the field once they see they have built a big lead so that they can ensure a higher success % on the Coopertition Bridge.

P.S. I really like the new shooter ;)

Re: Week 4 OPR - All regionals and districts
 

Don't the alliance partners also influence the OPR? For example, if you're at a tournament with a large number of robots that can't score, HP & TP will be lower than they would be at a different tournament. I will admit that I don't know exactly how OPR works, but this seems to be the case, at least for our results. Our GCK OPR is much higher than what we showed in STL and I see similar, lower, OPRs for other teams that went to the same two tournaments.

I in no way want to demean any particular tournament. St. Louis is a great regional -- well-run and in a nice facility. The teams there were all fantastic; it's just that there were a higher percentge of teams that couldn't score.

Re: Week 4 OPR - All regionals and districts
 

I usually take CCWM with skepticism, unless I'm looking for a defensive team or strategic specialist. I've seen instances that strength of opponents really impacts CCWM, but doesn't have much affect on OPR (unless it's a highly defensive game). In other words, if you play a tough schedule and lose all of your matches 85-80, your CCWM will suffer because of the number of losses. The OPR will show that you can put up a lot of points and the losses aren't likely your fault.

Re: Week 4 OPR - All regionals and districts
 

This is partially true. Your team's OPR is the least-squares approximation of how many points your robot can score in a match, which is based both on the number of points each of your alliances scores, and who was on each alliance. This basically means that if you're always on high-scoring alliances, you'll probably have a reasonably good OPR, but your OPR will be higher if your partners have lower OPRs and vice versa. (I can give a more detailed mathematical explanation of how OPR works if you like, but I think that post has probably been made already somewhere around here.)

Nice to see a high level of competition in the Miltown!

Re: Week 4 OPR - All regionals and districts
 

LeBron has yet to win "it" in *any* year.

Cue Koko Ed... :cool:

I'd love to know a way to determine elimination round OPR, but it's probably just as easy to post videos of the matches and say "Here, this is what we did". Go figure, I did that.

We serendipitously "found something" in the semis and finals in Wisconsin, and I think our driver is eager to continue it. I'm very much looking forward to Queen City. :)

Re: Week 4 OPR - All regionals and districts
 

For any given event, the alliances in the elims don't change. If you attempted to setup and solve Ax=b, you would find that A is rank deficient. There is no unique solution.

Translated into English: elimination data provides no insight into which team on the alliance is doing the scoring. So you can't calculate OPR from that data alone.

Re: Week 4 OPR - All regionals and districts
 

Given good enough videos, you could simply calculate the exact number of points scored by each robot.

Re: Week 4 OPR - All regionals and districts
 

Indeed, but such good videos aren't always available for all events.

It's fairly clear how many we score in Wisconsin in the vids I posted elsewhere, even though the angle is blar. The webcast folks did say they hope to share an archive of the event footage at some point in the future. Can't wait for that!

I guess the solution is for everyone to share more elimination round videos so we can see exactly how good teams are during crunch time! :)

Re: Week 4 OPR - All regionals and districts
 

the spreadsheet says our overall OPRs are 17.67 and 17.04 but the week 3 thread says our OPR was 11.25 for portland, which is what OPRNet says... and the first post in this thread says our OPR was 23.37 for seattle, which is also what OPRNet says...

so why are the numbers all so different?

we performed much better in seattle since we were working fully for most of our qualification matches, whereas in portland we were fully working only for our last 3 matches... so i can understand the 11.25 to 23.37 jump, but i don't see the minimal difference from 17.04 to 17.67...

Re: Week 4 OPR - All regionals and districts
 

17.31 is the average of your OPRs from Seattle and Portland, and the overall OPRs it gives you are your average, roughly, plus or minus .315.

Re: Week 4 OPR - All regionals and districts
 

The data you posted on total OPR are wrong. For teams that have played more than one event, you sometimes add up hybrid OPR, tele OPR and modified bridge OPR from different events together. That is why team 2046 numbers are quite a bit off and other teams are off too.

There is quite a bit of data pubilshed on CD already and they match each other perfectly. Everybody have access and choose the one that is more convenient for them to use. I like how you format your data, but please verify it before you publish so people are not confused.

Re: Week 4 OPR - All regionals and districts
 

Does anyone know why the Hawaii "Team Standing" data has STILL not been posted?

Attached is the Twitter data for Hawaii, from which the HP, BP, TP, and CP could be extracted. The usual warnings about Twitter data apply.

Re: Week 4 OPR - All regionals and districts
 

I have not seen the OPRs for Hawaii posted anywhere, so I am posting them here. This was calculated with just the qualification matches. I am working on an addition to The Blue Alliance that will calculate OPR automatically. The OPR data was generated using the code I wrote for TBA and match data from TBA. If someone can verify these OPRs, it would be much appreciated. :D

Re: Week 4 OPR - All regionals and districts
 

Looks correct. See PDF attached.

Re: Week 4 OPR - All regionals and districts
 

Since the Team Standing data for Hawaii has still not been posted, and apparently there is no effort underway to try to retrieve the data and post it, I thought I would try to reconstruct the Team Standing data from the Twitter data for the Hawaii Qual matches.

Toward that end, and given the unreliability of Twitter data, I invite everyone interested to review the Hawaii Qual match Twitter data and report errors here (based on videos or personal notes taken at the event).

For example, the Twitter data has two tweets each for Qual Matches 8 and 16, each with different data:

Does anyone know which is correct?

Re: Week 4 OPR - All regionals and districts
 

Here are the correct ones:
Matches 8 and 16 were replayed after Friday's Qualification Matches. On FRC-Spy, those matches are shown after Q-55, the last match.

Re: Week 4 OPR - All regionals and districts
 

Just curious: why were they replayed ?

Re: Week 4 OPR - All regionals and districts
 

No idea. I was watching the Webcast and the M.C. simply stated that those matches would be replayed. Perhaps someone who was at the Hawaii Regional could shed light on the reasoning behind the reasoning behind replaying these matches.

Re: Week 4 OPR - All regionals and districts
 

Those matches were replayed because the scoring system was not working for one of the alliances during those matches, as it was told to me by the refs when I asked.

Re: Week 4 OPR - All regionals and districts
 

Match 8 is because a volunteer inadvertently walked through the Kinect station in use during hybrid I believe.

In match 16, our alliance could not connect. Then, our opponents scores were not tallying. With those 2 fishy things happening on our side, a replay was allowed.

Re: Week 4 OPR - All regionals and districts
 

The Hawaii team standings are now posted.

Re: Week 4 OPR - All regionals and districts
 

If you click on this link:

http://www2.usfirst.org/2012comp/eve.../rankings.html

... it will take you to the Team Standings for Hawaii...

... but if you then click on the "Match Results" link, you will not get the Hawaii match results. The link has been broken.

How does one go about reporting an error on the usfirst.org website?

Re: Week 4 OPR - All regionals and districts
 

Is Week 5 OPR posted anywhere? I have searched for it and am coming up blank.

Re: Week 4 OPR - All regionals and districts
 

Re: Week 4 OPR - All regionals and districts
 

Try this. You should get a screen that looks like this.
