Rating movement formula

Team VIPR = average - (average - lower partner) * CRF, with CRF = 0.40.

Adjustment = 0.02 / (1 + 10 ^ (2.5 * (winner team VIPR - loser team VIPR))).

Winning partners both receive +adjustment. Losing partners both receive -adjustment.

Score margin is recorded for context but is not currently part of the v0.6 formula.

First game check: winner-loser VIPR diff +0.0127 -> computed delta -0.0096; 3.3060 -0.0096 = 3.2964
