Here's the average squared error in the match scores.
LS OPR (no prior): 3555.75
MMSE OPR (Oavg prior) : 3088.70
MMSE OPR (World OPR prior): 2973.91
MMSE OPR (regressed World OPR prior): 3000.04
I'll work on the 50 and 100 match splits and put them up later.
EDIT: I think I should elaborate a bit more on how I'm doing the priors. I've been adding a constant to everyone's World OPR so that the average of the OPRs is equal to Oavg. Essentially I'm saying that every robot improved by a constant. (These constants are very small, only Archimedes was greater than 1.5 points)
