Storyline
Dan Civitarese entered VIPR with an initial registry rating of 4.6330. Across 43 rated doubles games, the player went 22-21 and moved -0.2561, finishing at 4.3769.
Why It Moved
AI-generated explanation: The record was positive, but the rating dipped because the 22 wins added +0.0843 while the 21 loss(es) gave back -0.3404. The biggest single-game impact was -0.0193 against Mark Wu as partner and Sunil Sadhwani / Edward Gainer as opponents. In game #25 on 2026-09-03, VIPR expected the player's team to have the edge, so the loss carried a larger drop: player team 4.1088 vs opponent team 3.5320.
Partner Chemistry
Partnership patterns are starting to emerge.
Dan's most common partner signals so far: Robert Nunn (5-1, 83%), Sunil Sadhwani (3-2, 60%), Edward Gainer (1-3, 25%), Kevin Geraty (1-3, 25%). No partnership has reached both the 8+ match and 75%+ win-rate marker yet, so treat this as directional.

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 -0.1249 -> computed delta -0.0134; 4.6330 -0.0134 = 4.6196
