Re: "standard error" of OPR values

If combined with MMSE estimation to address some overfitting issues, it can occasionally result in improved match prediction compared to OPR, DPR, or CCWM measures. Even in years with a lot of defense though, it's not a whole lot better.
Seems a shame for such a meaningful statistic to be referenced not with a bang, but with a WMPR. ;->
