If a Regional's average score is higher than the World the possibility of teams' scores being artificially inflated by the performance of other teams. Therefore we normalize this by dividing this by the relative "strength" of the event. The general formula is: Normscore = Real Score x World Average / Regional Average

I haven't looked at the numbers from all the regionals, but I feel that it would work the other way: if you attend a very good regional, your OPR may be too low. If you have 3 teams that get 3 logos each and have a super fast minibot, there is no way for them to do that together and thus their OPR would be lower because of the fixed amount of total points, diminishing marginal returns in tubes scored, and having 3 robot getting in each other's way while scoring. I recall some teams at MSC had lower OPRs than at their district events. Unless I'm reading this wrong, 148's Dallas OPR is 5 times 217's from MSC.
Anyway, thanks again. We've used this since 2007 and its a good way to get a rough idea of how good a team is.
