Strength of Schedule
Best & worst strength of schedule for Top 10-ranked fighters.

Strength of schedule is determined by the fighter’s `540 Opponent Metric` – an experimental metric that 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.
