Steve's idea appears to be the same as mine, or at least his two equations are. I tried to implement it on tuesday, but it had bugs and I haven't had to time to get back to it. It is unfortunate that the matrix comes out as somewhat ill-conditioned, but I guess that isn't that terribly surprising since the amount of data we're processing is fairly small.

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+?
