You should also consider that, like last year, the best alliances will not be made up of twins and triplets. Each robot will fit into roles the others cannot in order for success.

From the '13 and '14 data I looked at, OPR had a very very high correlation with the new QA ranking system. Chart below shows OPR vs the old "Qualification Score" based on WLT, and the new "QA" system.
Note how events with more matches and fewer teams yield better data (all MAR events were 12 matches, '13 Archimedes was 9 matches, '14 Archimedes was 10 matches)
