What am I looking at?
Individual refs: stats for one official across all Avalanche games they worked, even with different partners.
Team baseline: the Avalanche went 445-337 (56.9%) across this sample. Ref win rates show how they compare to that team average.
Whistle differential: PIM differential. A positive number means opponents are penalized more often than the Avalanche.
Scores, PIM, and crews from NHL API. ATS/O-U from synthetic closing lines derived from final scores (12282/12282 games). Descriptive only, not market odds. Ref game counts rebuilt from DISTINCT game_id in game logs.
