Storyline

Phil Sciacca entered VIPR with an initial registry rating of 3.2500. Across 8 rated doubles games, the player went 3-5 and moved +0.0148, finishing at 3.2648.

Why It Moved

AI-generated explanation: The record was below .500, but the rating rose because the 3 win(s) added +0.0452 against stronger situations while the 5 losses cost -0.0304. The biggest single-game impact was +0.0176 against Mike Blackston as partner and Mike Fritz / Bruce Ashley as opponents. In game #6 on 2026-10-20, the player's team was the lower-rated team, so the win carried a larger gain: player team 3.4580 vs opponent team 3.8010.

Partner Chemistry

Partnership patterns are starting to emerge.

Phil's most common partner signals so far: Ed Carney (1-1, 50%), Kirstin Burri (1-1, 50%), Mike Blackston (1-1, 50%), Kerry Jewell (0-2, 0%). 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 +0.1793 -> computed delta -0.0053; 3.2500 -0.0053 = 3.2447
