That's really cool, thank you! The negative OPR threw me off for a while; it's strange how the top 90% has a higher total OPR than all teams.
Just some statistics I got from OPR data (I used column G on the "OPR results" tab from Ed Law's spreadsheet):
- The top 10 teams have a higher total OPR than the bottom 516 teams
- The top 0.5% of teams have a higher total OPR than the bottom 28.5% of teams
- The top 20 teams have a higher total OPR than the bottom 603 teams
- The top 1% of teams have a higher total OPR than the bottom 33% of teams
- The top 845 teams (47%) have 80% of the total OPR
- The top 388 teams (21%) have 50% of the total OPR
- The top 143 teams (8%) have 25% of the total OPR
What's really interesting is that following the stats above compared to the ones I had about QA, OPR seems to peak off more quickly, but have a larger "middle" section. I feel like part of the issue is that the OPR data I had only took the higher value for teams that have competed twice, as compared to the QA which had everything.
Graphing OPR vs QA gave me this:

Which seems to have a steeper curve in OPR, but not by as much as the stats imply. If I have some time I'll redo the OPR calculations with full data and check what I did for the QA ones.
