While OPR is relatively okay at predicting robot goodness, DPR is generally pretty bad at predicting a robot's defense capabilities. (especially in a game like this, how often does 1114 actually play defense?)
DPR is typically a good indicator of schedule difficulty though.

Actually its neither.
Its what I call an ETC - Estimated Team's Contribution
As a qualifying match gets added to my DB I add the alliance's points to a running sum for a given team. Leaving each team with a TAQMP (total alliance qualifying match points), then divide by the # of matches played and you get ATAQMP(average TAQMP)
then based on AT* go through all of the matches again, comparing the 3 teams AT*s on an alliance, and figure out the % of that matches points attributed to a given team ETQMC (estimated teams qualifying match contribution)
add up all the ETQMCs for a given robot and divide by the number of matches and you are left with ETC (Estimate Team's Contribution) on a per match basis.
what OPR lacks is a match by match analysis, it more looks that big picture and misses some of the details. Also next week i will be separating the total score into (autonomous & teleop) and the (minibot). This should reduce the point inflation and get an even more accurate ETC
so next week I'll have an EMC (estimated minibot contribution), ERC (estimated robot contribution), and an improved ETC
