| # | Player Team ( AVG ) | Opponent Team ( AVG ) | Winner-Loser VIPR Diff | Computed Delta |
|---|---|---|---|---|
| 1 | 4.2144 | 3.9682 | +0.2462 | +0.0039 |

| 3 | 4.0165 | 3.7592 | +0.2572 | +0.0037 |
| 4 | 4.0235 | 3.8816 | -0.1419 | -0.0139 |
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 +0.2462 -> computed delta +0.0039; 4.1430 +0.0039 = 4.1469
