Storyline
Jolynne Colvin entered VIPR with an initial registry rating of 3.6570. Across 12 rated doubles games, the player went 7-5 and moved -0.0006, finishing at 3.6564.
Why It Moved
AI-generated explanation: The record was positive, but the rating dipped because the 7 wins added +0.0564 while the 5 loss(es) gave back -0.0570. The biggest single-game impact was -0.0173 against Laura Marchisello as partner and Jean Narod / Sharon McFarland as opponents. In game #12 on 2026-07-23, VIPR expected the player's team to have the edge, so the loss carried a larger drop: player team 3.7403 vs opponent team 3.4169.

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 +0.1422 -> computed delta +0.0061; 3.6570 +0.0061 = 3.6631
