| # | Player Team ( AVG ) | Opponent Team ( AVG ) | Winner-Loser VIPR Diff | Computed Delta |
|---|---|---|---|---|
| 1 | 4.0982 | 4.3283 | +0.2301 | -0.0042 |
| 2 | 4.2891 | 4.1797 | +0.1093 | +0.0070 |
| 3 | 4.2777 | 4.0564 | +0.2213 | +0.0044 |
| 4 | 4.2878 | 4.1326 | -0.1552 | -0.0142 |
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 +0.2301 -> computed delta -0.0042; 4.2620 -0.0042 = 4.2578
