Storyline
Ron Ahart entered VIPR with an initial registry rating of 3.2400. Across 11 rated doubles games, the player went 6-5 and moved -0.0046, finishing at 3.2354.
Why It Moved

In game #5 on 2026-07-09, VIPR expected the player's team to have the edge, so the loss carried a larger drop: player team 3.2590 vs opponent team 2.9805.

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 +0.0422 -> computed delta +0.0088; 3.2400 +0.0088 = 3.2488
