The qualification ranking used in FRC is pretty poor. Even if you had some very good mathematical evaluation of robot performance (which in certain years, including this year, OPR is), it wouldn't correlate well because the standings are very often not a good evaluation of robot performance.

So really, there's a corollary to Lil Lavery's post:
-A bad performance indicator (OPR in his opinion) doesn't correlate well with another bad performance indicator (standard qual rankings with 8 matches played)
-Also, a good performance indicator (OPR in other's opinions) doesn't correlate well with a bad performance indicator.

Given the definition of OPR: "the average number of points a robot's presence adds to its Alliance's score", the real question about OPR is not whether it predicts final standings, but rather whether it accurately predicts an upcoming match score given the input of matches played before.
