Storyline
Perry Olson entered VIPR with an initial registry rating of 5.2670. Across 12 rated doubles games, the player went 8-4 and moved -0.0196, finishing at 5.2474.
Why It Moved
AI-generated explanation: The record was positive, but the rating dipped because the 8 wins added +0.0336 while the 4 loss(es) gave back -0.0532. The biggest single-game impact was -0.0178 against Gary Kray as partner and Michael Leardi / Tony Toledo as opponents. In game #3 on 2026-09-03, VIPR expected the player's team to have the edge, so the loss carried a larger drop: player team 4.8229 vs opponent team 4.4560.

Formula Homework
These rows show the team ratings used in the adjustment calculation. The computed delta is the signed rating change produced by the current v0.6 formula.

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 +0.3344 -> computed delta +0.0025; 5.2670 +0.0025 = 5.2695
