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.
