| # | Player Team ( AVG ) | Opponent Team ( AVG ) | Winner-Loser VIPR Diff | Computed Delta |
|---|---|---|---|---|
| 1 | 3.4966 | 3.4587 | +0.0379 | +0.0089 |

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 +0.0379 -> computed delta +0.0089; 3.4870 +0.0089 = 3.4959
