Also introducing a funky new metric, EPR, which uses 3 simultaneous equations for each match:
1) r1+r2+r3-b1-b2-b3 = RS-BS
2) r1+r2+r3=RS
3) b1+b2+b3=BS
... and solves all the equations simultaneously.

How do you interpret these new EPR values? They look closer to an OPR than a WM-measure as #2 and #3 both only factor in offense. How will you measure its performance? Perhaps by comparing the overall residual of all 3 combined vs. other ways of predicting all 3 (e.g., using WMPR for #1 and standard OPR for #2 and #3)?
