Storyline
Joseph DeVito entered VIPR with an initial registry rating of 3.8060. Across 28 rated doubles games, the player went 16-12 and moved -0.0004, finishing at 3.8056.
Why It Moved
AI-generated explanation: The record was positive, but the rating dipped because the 16 wins added +0.1277 while the 12 loss(es) gave back -0.1281. The biggest single-game impact was -0.0193 against George Carroll as partner and Brian Leonard / Jimmy Bowes as opponents. In game #6 on 2026-07-23, VIPR expected the player's team to have the edge, so the loss carried a larger drop: player team 3.7378 vs opponent team 3.1557.
Partner Chemistry
Partnership patterns are starting to emerge.
Joseph's most common partner signals so far: Jimmy Bowes (3-2, 60%), George Carroll (1-2, 33%), Craig Vogel (2-0, 100%), Edward Gainer (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.
