Storyline
Mark Wu entered VIPR with an initial registry rating of 4.0260. Across 48 rated doubles games, the player went 27-21 and moved -0.0467, finishing at 3.9793.
Why It Moved
AI-generated explanation: The record was positive, but the rating dipped because the 27 wins added +0.2165 while the 21 loss(es) gave back -0.2632. The biggest single-game impact was -0.0197 against William Danny Webster as partner and Chris Donahue / Ramon Jimenez as opponents. In game #2 on 2026-08-06, VIPR expected the player's team to have the edge, so the loss carried a larger drop: player team 3.9951 vs opponent team 3.2431.
Partner Chemistry
Partnership patterns are starting to emerge.
Mark's most common partner signals so far: Sunil Sadhwani (4-1, 80%), Craig Vogel (2-3, 40%), Robert Nunn (3-0, 100%), Kevin Battle (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 +0.5732 -> computed delta +0.0007; 4.0260 +0.0007 = 4.0267
