Why It Moved

The biggest single-game impact was +0.0194 against Ramon Jimenez as partner and Craig Vogel / Tim Tonguis as opponents. In game #5 on 2026-07-23, the player's team was the lower-rated team, so the win carried a larger gain: player team 3.2025 vs opponent team 3.8130.

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 +0.0461 -> computed delta -0.0087; 3.7950 -0.0087 = 3.7863
