Formula Homework

These rows show the team ratings used in the adjustment calculation. The computed delta is the signed rating change produced by the current v0.6 formula.

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 +0.1661 -> computed delta +0.0056; 3.4970 +0.0056 = 3.5026
