Storyline
Ellen Huber entered VIPR with an initial registry rating of 3.4170. Across 8 rated doubles games, the player went 3-5 and moved +0.0408, finishing at 3.4578.
Why It Moved
AI-generated explanation: The record was below .500, but the rating rose because the 3 win(s) added +0.0535 against stronger situations while the 5 losses cost -0.0127. The biggest single-game impact was +0.0181 against Mike Blackston as partner and Mary Seifert / Douglas Starn as opponents. In game #2 on 2026-10-13, the player's team was the lower-rated team, so the win carried a larger gain: player team 3.5759 vs opponent team 3.9632.

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 +0.4126 -> computed delta -0.0017; 3.4170 -0.0017 = 3.4153
