Why It Moved

The biggest single-game impact was -0.0131 against Mary LaFrancois as partner and Nancy Krau / Barbara Amato as opponents.

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.
