Back for 2026! There have been some tweaks (noted below by strikethroughs and blue text.)
Fights considered must satisfy all of the criteria below:
- Both fighters must be active (fought in 360 days prior to event). Reduces uncertainty.
Both fighters must have at least 5 fights, with at least 1 draw or 1 loss (excluding debut). More data makes WHR happy.- Both fighters must have at least 7 fights in the prior 7 years, including 1+ loss. If the loss was in their debut, then 2+ losses are required.
- Both fighters must be rated in the same division as the fight. Further reduces uncertainty.
- Must have odds from at least three bookmakers.
