An improvement to OPR

[Citrus Dad]

Note that the OPR parameters are like any other statistical measure and have standard errors associated with those parameters. I haven't seen the SEs posted with the OPR parameters, but I can tell you that the SEs are likely to be VERY large for so few observations--only 8 per team at the Champs, at most 12 in any of the regionals. The OPRs are useful indicators, and probably can be used in a pinch if you lack other data, but they are highly unreliable for live scouting. I wouldn't bother calculating them on the fly at a competition. (The CCWM and DPRs appear to be even less reliable).

Our team had an OPR of 43 on Curie, yet our own scouting data showed we were scoring over 62 per match--quite a discrepancy. 4814 showed a CCWM ranked only 33rd yet went undefeated, and our defensive scouting data confirmed that they had substantial value added.
