What is the Bias Score and how is it calculated?

The Bias Score compares a team's win rate under a specific referee to their baseline win rate (45%). A negative score suggests the team performs worse than average under that referee.

What sample size is considered reliable?

We recommend at least 5 games for initial patterns and 10+ games for high confidence.
