I'll try again to implement this new matrix tonight, and I'll plug it into my prediction code to see if it is any better than the more basic OPR/DPR stats.
We need to come up with a name for this more-complex stat: how about OPR+ and DPR+?

I figured as much, and am glad you have had more success in implementing it than I have! I tried to get my son, a senior in college - Comp Sci/Math Major to help me ... but "NO" he didn't have time to help me with my "homework'!
I like the idea of OPR+ and DPR+ to indicate the additional complexity of the stat. I'd love to see what you are able to do, as well as how predictive the resulting values are. Thanks for all your hard work and your efforts! If there is anything I can do to assist or push this along, just let me know!
