Storyline

Jackie Minyard entered VIPR with an initial registry rating of 3.4510. Across 20 rated doubles games, the player went 11-9 and moved -0.0153, finishing at 3.4357.

Why It Moved

AI-generated explanation: The record was positive, but the rating dipped because the 11 wins added +0.0918 while the 9 loss(es) gave back -0.1071. The biggest single-game impact was -0.0139 against Lori Novack as partner and Amy Huckaby / Connie Nowell as opponents. In game #10 on 2026-08-13, VIPR expected the player's team to have the edge, so the loss carried a larger drop: player team 3.2743 vs opponent team 3.1330.

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
