Why It Moved
AI-generated explanation: The record was below .500, but the rating rose because the 3 win(s) added +0.0403 against stronger situations while the 5 losses cost -0.0272. The biggest single-game impact was +0.0162 against Sal Aparo as partner and David DeBeradinis / Chris Eversole as opponents. In game #6 on 2026-07-23, the player's team was the lower-rated team, so the win carried a larger gain: player team 4.1222 vs opponent team 4.3748.
Partnership patterns are starting to emerge.
Richard's most common partner signals so far: Bill Shoemaker (1-0, 100%), Jerry Linklater (1-0, 100%), Sal Aparo (1-0, 100%), Chris Eversole (0-1, 0%). No partnership has reached both the 8+ match and 75%+ win-rate marker yet, so treat this as directional.
Richard has faced David DeBeradinis 3 times - record: 1-2. A close matchup worth watching.

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.
