Important: “fight impact” here means historical context, not causation. A referee does not choose the matchup, fighter styles, skill gap or scheduled length, so finish/decision rates must be interpreted with sample size and those confounders in mind. Historical title-fight flags are still being normalized, so PropBetEdge does not publish a referee title-assignment total yet. Referee tendencies will only appear in Pregame Desk when a specific assignment is verified and the sample clears the minimum-data gate.
