Strength of Schedule
Issue Date: 9/28/2025 (Official Release: #991)
Strength of Schedule
Strength of schedule is determined by the fighter's `540 Opponent Metric` - a secondary metric that in combination with the fighter rating, attempts to reflect a fighter’s recent opposition quality. The metric goes back 1,080 days, and looks at all the fighter’s opponents’ W-L-D records within a window of 540 days before, and 540 days after their respective bout(s) with the fighter. All of the records are added up and the cumulative win percentage is presented by this metric in a `strength of schedule` format.Best Strength of Schedule Among Top 10 Male Fighters
