Someone did a study for Archimedes this year. I would say it is similar to 2011 where 3 really impressive scorers would put up a really great score, but if you expected 3X, you would instead get more like 2.25 to 2.5....
I produced predicted scores for Newton using the OPR components to eliminate potential double counting of auto and adjust for coop points. I predicted 118 would average 200 and they averaged 198. I have to check the distribution of OPR vs actual points.
