Re: Easy to use Offensive Power Rankings (OPR) program for mid-regional scouting

I found that it doesn't matter if you solve the matrix based upon win margin or if you just subtract DPR from OPR, the number is still the same. The CCWM is based upon the white paper that I saw Ed Law put out at the end of last year, which is what I originially tried to implement in the matrices. When I saw that the numbers were the same, I simplified all of the code and didn't rename the stuff -- oversight on my part.

CCWM = Caclulated Contribution to Winning Margin
aka PlusMinus Rating, i.e. different calculations to arrive at the same solution.

I think you want a high OPR for a first round pick, then a high CCWM for the second round... that is, if you want a high-octane, excitingly offensive alliance (which is my preference).
