Partnership patterns are starting to emerge.
Sue's most common partner signals so far: Barbara Amato (1-0, 100%), Elena Gordon (1-0, 100%), Joy McCormick (1-0, 100%), Mary LaFrancois (1-0, 100%). No partnership has reached both the 8+ match and 75%+ win-rate marker yet, so treat this as directional.

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.
