See attached XLS. I was playing around with it yesterday. There's all sorts of fun things you could try.
Column D looks a lot like what you're suggesting, except it adds the average OPR instead.
Also attached are 2013 A b T for OPR CCWM WMPR and EPR. The raw qual match data from TBA used to generate those is posted
here.

| -1 -1 -1 2 2 2 | |b3| = |2BS - RS|

Each match generates 3 equations (3 rows in the A matrix and 3 scores in the b matrix).
If you look at _Aepr.CSV (or _Aepr.dat) and _bepr.CSV (or _bepr.dat) it should be pretty clear.
Then you solve for EPR like so:
EPR = pinv(Aepr)*bepr
If you want to see what the matrix for the normal equations looks like, look at Method 2 in
this post. N will be square.

Just kidding.
