Feel free to change it up and add any functionalities. (i.e sort by regional, etc.)

Once again, thanks to Bongle for his work on OPR over the years to make it very easy to use and comprehend.

Interesting things show up in the spreadsheet you posted because teams have multiple entries. It's a bit easier to see consistency (although to be in the top 100 I limited it to, you're pretty consistent already if you made it there twice). These teams show up more than once (I know this isn't perfect because there are some awesome teams out there that haven't competed twice yet):

• 67 claims the top two spots.
• 341 claims THREE spots in the top 10 (4,6,9)
• 2056 claims two spots in the top 10 (3,7)
  
• #: Rankings
• 16: 38 and 42
• 48: 28 and 43
• 148: 73 and 75
• 340: 45 and 59
• 365: 11 and 82
• 399: 44 and 57
• 469: 19 and 39
• 488: 29 and 72
• 610: 30 and 93
• 967: 66 and 95
• 1114: 14 and 22
• 1208: 87 and 88
• 1218: 40 and 41
• 1477: 25 and 63
• 1507: 12 and 17
• 1629: 24 and 79
• 1714: 53 and 70
• 1983: 5 and 16
• 1986: 13 and 36
• 2169: 27 and 56
• 2474: 10 and 46
• 2826: 52 and 74

Together, these 25 teams account for 51 spots in the top 100.

6 of the top 30 OPR performances of the season have been produced by Canadian teams.

All but one of those Canadian teams has qualified for STL, with only 3161 being on the outside looking in.

3161 was also the team which had a chance to snatch the #1 seed away from 1114 in their last match at Waterloo. They held the tiebreaker over 1114 with a higher Hybrid Points total.

This is the match where it all happened, and also contains a "triple double" with all 6 robots balanced...

Here is the average rank of each of those 25 teams, sorted. Take note of the important fact that these are just some numbers, and probably will not be a good predictor of all that much. Except maybe which team has a better average OPR rank out of teams with two spots in the top 100 as of Week 4, it'll help a lot for that.

Suits me! You just helped me make my Top 25 list - promote the teams that have won 2+ events, then 1 win + finalists, lather rinse repeat. Fill in the top performing single-competition teams, bump 2826 up because I saw how awesome they were in Wisconsin elims and I know this OPR stuff doesn't measure those performances, and finis.

The only issue with using the average OPR is that is disregards changes made between competitions and leads to an inacurate ranking. I think ranking the OPR's from teams leatest event is a more accurate way to rank teams via OPR because it represents what teams are doing currently not in week 1 or 2. An example of this is 365, in week 2 at chestnut hill district they had an OPR of 21.2 ranking 82nd over all while week 4 at Lenape with a new shooter 365 had an OPR of 31.1 ranking 11th or using teams latest event's OPR ranking 7th.

This is definitely a limitation of OPR. I am not sure how valid it is to compare OPRs across events at all, for that matter. I am a much bigger fan of CCWM (OPR+DPR), since it better reflects contributions to score DIFFERENTIAL rather than raw score itself. Many top teams leave a lot of potential points on the field once they see they have built a big lead so that they can ensure a higher success % on the Coopertition Bridge.

P.S. I really like the new shooter

Don't the alliance partners also influence the OPR? For example, if you're at a tournament with a large number of robots that can't score, HP & TP will be lower than they would be at a different tournament. I will admit that I don't know exactly how OPR works, but this seems to be the case, at least for our results. Our GCK OPR is much higher than what we showed in STL and I see similar, lower, OPRs for other teams that went to the same two tournaments.

I in no way want to demean any particular tournament. St. Louis is a great regional -- well-run and in a nice facility. The teams there were all fantastic; it's just that there were a higher percentge of teams that couldn't score.

This is partially true. Your team's OPR is the least-squares approximation of how many points your robot can score in a match, which is based both on the number of points each of your alliances scores, and who was on each alliance. This basically means that if you're always on high-scoring alliances, you'll probably have a reasonably good OPR, but your OPR will be higher if your partners have lower OPRs and vice versa. (I can give a more detailed mathematical explanation of how OPR works if you like, but I think that post has probably been made already somewhere around here.)

I usually take CCWM with skepticism, unless I'm looking for a defensive team or strategic specialist. I've seen instances that strength of opponents really impacts CCWM, but doesn't have much affect on OPR (unless it's a highly defensive game). In other words, if you play a tough schedule and lose all of your matches 85-80, your CCWM will suffer because of the number of losses. The OPR will show that you can put up a lot of points and the losses aren't likely your fault.
