Storyline
Lori Mueller entered VIPR with an initial registry rating of 4.3580. Across 8 rated doubles games, the player went 6-2 and moved -0.0017, finishing at 4.3563.
Why It Moved

In game #6 on 2026-08-20, VIPR expected the player's team to have the edge, so the loss carried a larger drop: player team 4.0194 vs opponent team 3.8357.

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.
