Adambots Automated Scouting Kit

Any idea why so many of the OPR values differ so much from Ed Law's and FRC Tracker's numbers?

I spot-checked a few teams and didn't find any differences. Are you sure you're comparing the kit with Ed's per-event OPRs rather than the World versions?

This is fantastic, Adambots! Thanks.

Ed Law's Championship V4, Archimedes tab (and FRC Tracker, Archimedes data) has 987's OPR listed as 106.9 while Adambots lists OPR as only 85 and change for the division. Several other teams are listed lower as well same and other divisions.

There is an issue that was identified and discussed in another post. The problem arises when there are surrogate matches.

Currently, OPR is calculated using all matches and scores. Even surrogate matches for teams are included in the calculations. However when we calculate OPR for autonomous, teleop and climb, the total points used in vector b of Ax=b does not include surrogate matches, but the matrix A contains all the matches. This makes your team's auto, teleop and climb OPR smaller because you played 9 matches but only have scores for 8 matches. It is like you get zero for everything for one match.

Hence 106.9 for overall OPR is correct. 85.4 came from adding the auto, teleop and climb OPR and it is wrong.

This is one of my summer project to do. I have a few different ideas how to compensate for it, but I want to pick one that is most mathematically sound.

Thanks for the clarification, Ed! And please know that all of your effort is deeply appreciated.
