These rows show the team ratings used in the adjustment calculation. The computed delta is the signed rating change produced by the current v0.6 formula.
| # | Player Team ( AVG ) | Opponent Team ( AVG ) | Winner-Loser VIPR Diff | Computed Delta |
|---|---|---|---|---|
| 1 | 3.4555 | 3.5124 | -0.0569 | +0.0116 |
| 2 | 3.4789 | 3.4225 | +0.0565 | +0.0084 |
| 3 | 3.4206 | 3.4720 | -0.0513 | +0.0115 |
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 -0.0569 -> computed delta +0.0116; 3.4590 +0.0116 = 3.4706
