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

I just use the official FIRST match results.

frclinks.com gives you links to most of them.

Example: The Alamo results are here: http://www2.usfirst.org/2012comp/Events/stx/matchresults.html (stx is the short code for the regional). You can get different results by substituting different regional codes and years.

Is there a way to grab the data from all of the events?

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

It strikes me that OPR might undervalue teams who exclusively pursue the Coopertition Bridge in qualification rounds, since that doesn't add to their score. Have you considered accounting for that, perhaps by adding twenty points to the score of any alliance that receives full coopertition points?

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

It would undervalue them for sure. Unfortunately, I don't actually have a way to determine which alliance earned coopertition points, since it's not in the full results and I don't have the time to implement a twitter parser.

Another thing it is semi-missing is foul points - in previous years, a team that tended to take penalties would end up with a negative OPR. But this year, since those penalties actually add points to your opponents, a penalty-heavy team might still have an apparently-high OPR. Or, if you are a team that tends to get fouled, you might have an elevated OPR despite never scoring a basket.

Here's all the OPRs for this week. The number on the left is that robot's rank at its regional.

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

We went for the coopertition bridge every match, usually with at least 45 seconds left in the match. I'm sure that hurts our OPR, but anyway...

You also don't have a way to determine which robots scored the points in each match, which is why we use OPR. You can use the OPR algorithm on coopertition points to get a "coopertition OPR" that should in theory determine which robots are doing the coopertition bridge balancing.

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

The problem is that for every match, I at least get a (foul + baskets + bridge) score for each alliance, which is then used to determine OPR. I don't, however, get a coopertition score for each alliance every match, so you can't apply the same regression math to try and tease out which teams actually earned the coopertition bridge points. With the data actually available in the FRC results, the best you can do is divide each team's CP total by their # of matches played, and hope that correlates with the teams that are actually cooperteting.

If I could parse the twitter feed or if it was available at a more convenient place than twitter (anyone know a link?), then I'd be able to break out fun things like Bridge Power Ratings, Hybrid Ratings, Basket Power Ratings, Foul Ratings, and Coopertition ratings, which would probably help a prospective picking team pick out complementary teams. Come to think of it, that would be useful enough to be worth trying to do.

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

Ahhh, for some reason I thought they were giving the coopertition bonus in the results. I was competing this week so I haven't seen what the web results look like this year.

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

If you're using an n x n+1 matrix where the n+1 column is the sum of points, can you not use the sum on the standings page under the CP column?

For example

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

By this theory, you could also do separate "OPR's" for Hybrid Points, Bridge Points, Teleop Points, and Coop Points. That would be interesting to see.

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

If you really want to, you can pull the standings, and take the CP points/possible CPs * Bridge Points. I think one could make a reasonable argument that each teams contribution towards teh Co-Op bridge should be worth 10 points if successful. Thus for Kettering, looking at the top 2 rankings, you could argue that 2337 deserves a 14CP/(2CP*12matches)*10 points or... 5.8 point bonus. 51 would get 10CP/(2CP*12matches)*10 or 4.17 bonus. You would need to do that in relation to all teams to get a full understanding, and even then it only tells a partial story.

OPR will be an interesting metric this year. While not as low a value as it was in 2009, I expect it will not be as strong a predictor as it was in 2008 or 2010. Smart teams will be looking at what is seeding high, and what is winning, and thus what are good predictors.
Further discussion should probably be in an outside thread so as not to thread-jack Bongle any further than I have.

Thank you Bongle for posting the OPRs.

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

Yeah, I thought of that after I posted :). In fact, I was completely wrong in my previous post - all you need to do an OPR-style calc is the sum of the points scored and what alliance partners that team throughout the regional, so the standings page will in fact be able to give us all the things we want wrt bridge/basket/foul/coopertition points. The individual match scores are actually not necessary (except in past years, FIRST didn't break out the sum of a team's scoring types, which is why I thought the lack of CP/HP/BP/FP in the match scores was a deal-killer).

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

Alright, starting work on the bridge/basket/foul/coopertition analysis component now. I'm pretty excited. Hopefully done in a few hours (8pm EST).

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

Ok, here's v19. This includes, for 2012, the ability to rank teams on hybrid/bridge/teleop categories. I assumed that 2 coopertition points = 10 points of bridge scoring.

I may have skipped a version number.

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

OK, I'm running Win 7 x64. When I run OPRNet from a command line, I get an error saying MSVCP100.dll is missing.
I re-installed it, but the error keeps popping up every time I try to run OPRNet.
Any clue what's happening and how to cure this?

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

Try installing the Visual C++ 2008 runtimes: http://www.microsoft.com/download/en/details.aspx?id=29

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

Nope, same error after install.
