What we saw more of was many weak regionals where only 1-6 teams could score effectively, as such there were considerably lower scores. (Events with elimination matches where only 7 points were scored, etc.)
I think that linearly scaling the entire average contribution or OPR skews it too much at weaker regionals. Based on the two events 330 attended, Arizona was much weaker then LA, as the statistics show. Our performance was also worse at Arizona. With the current scaling, the Average Offensive Score scaling is 113.7 at Arizona and 79.5 at LA. The Arizona value is very much over inflated. I think a better scaling would be
Code:
normalized value = (team - regional average) + worldwide average
This results in an AZ offensive score of around 67, which makes sense to me. This way you're only compensating for the regional difference, and not the teams performance.

Thank you to Geoff Allan, Ben Bennett and Roberto Rotolo!
