Storyline

Joe Spano entered VIPR with an initial registry rating of 4.0650. Across 32 rated doubles games, the player went 18-14 and moved -0.0327, finishing at 4.0323.

Why It Moved

AI-generated explanation: The record was positive, but the rating dipped because the 18 wins added +0.1274 while the 14 loss(es) gave back -0.1601. The biggest single-game impact was -0.0197 against Frank Pindulic as partner and Ramon Jimenez / George Carroll as opponents. In game #9 on 2026-07-16, VIPR expected the player's team to have the edge, so the loss carried a larger drop: player team 3.8558 vs opponent team 3.1459.

Partner Chemistry

Joe's most common partner signals so far: Christopher Burns (2-1, 67%), Jeff Fink (1-2, 33%), Craig Narod (2-0, 100%), Scott Konkel (2-0, 100%). 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 -0.0963 -> computed delta -0.0127; 4.0650 -0.0127 = 4.0523
