Go to Post I find this ironic. In English class our teacher's tell us how there is symbolism and such, and we don't understand it or think its there. Then FIRSTer's get a Game Hit, and we think EVERYTHING is a symbol and has some significance. - akoscielski3 [more]

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

I have a general question that I would love for you all to consider. I am a firm believer in the OPR/DPR concept, and included it in our team's scouting application. But what I found was that in this game, ALLIANCE data in a match is not that helpful. If a really good team has an alliance with two essentially non-functional robots in 2 or 3 of your matches - the numbers look terrible for that team. A case in point, 234 (Cyberblue) at the DC regional - if you look at the OPR numbers for them, they are in the middle of the pack. Our scouting team did NOT look at the alliance data this year. I had scouts answer the following questions:
1) How many MR did they place in a trailer (including their own in the event they were trying to avoid the penalty)
2) How many MR were in their trailer (by either the opposing alliance, or the HP)
3) How many EC did they deliver to be exchanged with a SC

I then calculated the OPR and DPR on those stats. In my example above, regarding 234 - they jumped from middle of the pack, to essentially the same level as 45, which is where they should have been ranked.

Any one else looking at TEAM OPR and DPR, and if so, how are you doing it, and what were your results like.

By the way, when I looked at the predictive nature of the values we calculated, we were right in our predictions more than 85% of the time. Only something like "forgetting to turn on the radio" or some such issue would throw off the results.

Best regards,

Steve
