Its week 1 and week 2 regionals.

There appear to be many anomalies in the analysis. See attachment.

Some teams are listed twice, with different OPRs, for the same week.

Several teams are listed 3 times with different OPRs.

Ill fix those tommrow. Thanks for pointing out sorry for the mistakes.

Raw data is available to compute separate power ratings for Hybrid, Bridge, TeleOp, and Foul Points*.

Would that be of interest to anyone ?


*Foul Points would be computed for the Team committing the foul.

Ether I can add hybrid teleop and bridge balancing rankings tommrow, if you wish?

I should have been clearer. When I said "TeleOp" I meant a TeleOp hoop power rating. Be aware that the "TeleOp" in the data you are using is actually TeleOp hoop plus Foul Points.

What version of OPRNet did you use to calculate these?

Yes! Raw data would be awesome!

Yes, that was done in the week 1 OPR thread and it was really cool.

Here is the raw match-by-match data for weeks 1 and 2 in an Excel spreadsheet.

This includes qualification, elimination, and practice data for all regional and district events which have taken place so far this season, with the exception of Oregon and Traverse City.

It includes Bridge, Foul, Hybrid, TeleOp hoops, and Coopertition data for each match.

Could you do it like it is in the week 1 thread? It would make it easier to read for each team.

I don't understand where the error came from if the OP used oprnet to calculate the OPR.

This has been discussed before but for those that didn't catch it, I will repeat it again. We should not compare OPRs across different regionals/district events. It looks like that is what the OP did. The reason is some events are stronger than others and it is not a fair comparison. The better way to do it is what I called True World Ranking where every match including elimination rounds of every regional/district are all assembled into a giant matrix so all interactions between teams are taken into account. It is not perfect but it will give each team one OPR number that is a reflection of their whole season so far.

This year I also calculated the OPR for hybrid, bridge, teleop and cooperition separately using the same method. I publish all these data after each week in the following CD link if anyone is interested.

I pasted the week 1 events wrong ED. Thats where the error came from.

Basically, yes... OPR (Offensive Power Rating) is an approximation at how many points your team scores in the average match. Since the co-op bridge doesn't provide any points, it's not included, even though it's a testament to the value of your robot.

The CP bridge is included in OPRNet this year - I treat it as 5 points per CP point that your alliance earns, since there is an opportunity cost aspect to it. A balanced CP bridge could have been a single robot on a balanced alliance bridge.

Same with the separate 'bridge' calculation - since your robot's bridge skills are clearly related to your ability to balance the CP bridge.

I'm not sure if I still think it's a good idea including it in the overall OPR calculation, but it's too late for me to take it back out now.

I decided not to assign points for Coopertition points and just calculate OPR for Coopertition bridge as is. So that number represents number of Coopertition points per match. Teams can assign their own point value to it and add to the OPR of bridge points if they like. My philosophy has always been encouraging teams to customize the spreadsheet for their own need so I don't decide how they should modify the data.

Our first hand experience competing at an event this year shows that it is easier to balance with your own alliance partner than with someone who is over 50 feet away from you. This is the reason I want to look at balancing alliance bridge and coopertition bridge separately.
