I earlier tried to include the use the eliminations for the Florida Regional like Sumadin and the results were very skewed. So the matrices have a problem when the elimination match data is used to solve the matrix. I am still puzzled as to why the eliminations skew the OPR results so drastically (8,8 OPR no elims versus 1.47 OPR with elim)
233 and 1251's OPR add to 81, so overall the alliance underperformed* based on the qualifying OPRs. Therefore all three robot's OPRs should go down a little. Those 6 elim matches were 20% of the matches that 233 and 1251 played this year (they went to other regionals too). It was over 40% of 86's matches this year, so 86 would see more of an effect.

Also 233 performed much better at Hawaii then they did in Florida. Since there is only one OPR for the year, it looks like Pink underperformed at Hawaii and overperformed at Florida. I think that 86's OPR would change less when adding in the elims if you were looking at the Florida data only.

*by underperformed, I mean as far as OPR is concerned. It's likely that more defense was played in the finals and was the cause.
