It is similar to Boggle's concept above, and may be essentially the same result, but can't figure out how to parse the data to actually make it happen, especially since it creates a 2N x 2N matrix...

Two equations:
1. (Xioblue + Xjoblue + Xkoblue) - (Xldred + Xmdred + Xndred) = Scoreblue
2. (Xlored + Xmored + Xnored) - (Xidblue + Xjdblue + Xkdblue) = Scorered

Where ...
............X
..............io (Team i - OPR)
................blue (Alliance)

and likewise, id would represent Team i - DPR.
You would have to solve for both the OPR and DPR for each team.

OK, so either your idea is identical to Bongle's, or I misunderstood him, because what you explained above is exactly what I implemented. Bongle's been away from the topic for a while, hopefully he'll see this and let us know if that's what he meant.
