|---|---|---|---|---|
| 1 | 3.0445 | 2.7183 | +0.3262 | +0.0027 |

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 +0.3262 -> computed delta +0.0027; 3.0490 +0.0027 = 3.0517
