Calculated OPR for week 1 events. Enjoy
Team# OPR
Thanks for posting! Nice to see that we made the top 30!
Wow. It’s cool being second, but 341 looks to have a huge lead on the entire field here. Can’t wait to find some video and check out what makes them so good.
This will sound TOTALLY noob, but…
What is OPR? (for the sake of everyone else too)

Did you use just the qualification data from this past weekend’s events, or did you include elims and/or other event data ?
Also, where did you get your Gull Lake data ?

Offensive Power Rating. There are threads discussing what this is.
Here’s one:

For more, just search for OPR in the title.
Does the formula implicitly take foul points into account? Is there any way (or reason) to extract penalties from scores for the OPR calcs? Points from fouls are displayed on the scoreboard at the end of each match, but I haven’t seen that data recorded anywhere.
Thanks for putting this together and sharing it!

Thanks for posting this.
Are people counting coopertition balancing as points in OPR?

The @frcfms twitter feed keeps track of foul points in matches.

The proper way to determine fouls would be to use both pre-foul and post-foul DPR (Defensive Power Rating) metrics. Find both DPR numbers, then subtract the pre-foul from the post-foul number to determine a foul rating. I think this will find the few teams who commit 1+ fouls per match (with a rating of 1.0 or more), while most teams will have a rating between 0 and 0.33 (once every 3 matches someone on their alliance committed a foul). Anyone with a rating of 3.0 or more probably didn’t read the rule book…
Of course, there will always be outliers – such as the random robot that gets teamed with the box on wheels that bangs on the opponent’s colored bridge during a balance.

If I understand correctly, the average team nets barely 5 points per game after penalties. Also, almost one in six teams does more harm than good (negative OPR).
Makes you want to really be careful, and be sure that your drive team knows how to not make a penalty.

Based on their robot design (gatherer pointing backwards) and big OPR lead, I’m guessing that 341 reloaded and scored extra points in Hybrid?
Sorry I forgot Gull Lake. Thanks for pointing it out.

Thank you. frclinks.com does not have the MIGL event code listed.
All,
I am concerned that the OPR data this year is grossly misleading if there is not some consideration for the Coopertition points. What I noticed from Kettering (and some other regional events from the web casts) is that the top teams are prioritizing on the Coop bridge over the regular bridge.
We need to figure out a way to incorporate Coop points if we want OPR to be meaningful. Right now I am not going to use OPR for much decision making in its current form.

Once he is done with the formula I will post the results using the new formula.
