Storyline
Roy Strasburg entered VIPR with an initial registry rating of 3.3310. Across 36 rated doubles games, the player went 19-17 and moved -0.0232, finishing at 3.3078.
Why It Moved
AI-generated explanation: The record was positive, but the rating dipped because the 19 wins added +0.1514 while the 17 loss(es) gave back -0.1746. The biggest single-game impact was -0.0141 against John Kaufman as partner and Ron Ahart / Jerry Johnson as opponents. In game #32 on 2026-10-01, VIPR expected the player's team to have the edge, so the loss carried a larger drop: player team 3.3575 vs opponent team 3.2051.
Partner Chemistry
Partnership patterns are starting to emerge.
Roy's most common partner signals so far: Eric Jones (3-1, 75%), Jerry Johnson (2-2, 50%), Gregory Kerr (3-0, 100%), David Roman (2-1, 67%). 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 +0.0234 -> computed delta -0.0093; 3.3310 -0.0093 = 3.3217
