Storyline
Jackie Minyard entered VIPR with an initial registry rating of 3.4510. Across 24 rated doubles games, the player went 13-11 and moved -0.0260, finishing at 3.4250.
Why It Moved
AI-generated explanation: The record was positive, but the rating dipped because the 13 wins added +0.1095 while the 11 loss(es) gave back -0.1355. The biggest single-game impact was -0.0151 against Kathy Battle as partner and Lori Novack / Debbie Fischer as opponents. In game #21 on 2026-09-17, VIPR expected the player's team to have the edge, so the loss carried a larger drop: player team 3.3665 vs opponent team 3.1708.

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 -0.0215 -> computed delta +0.0106; 3.4510 +0.0106 = 3.4616
