How Fighter Elo Works

Fighter Elo is the model's rating for a fighter, on the same scale chess uses. An average UFC fighter sits around 1500. The gap between two fighters sets the forecast: 100 points ahead is about a 64% chance to win, 200 points about 76%, and 400 points about 91%.

Classic Elo only moves on wins and losses. Fighter Elo also counts how the fights went (striking and grappling numbers), age and build, and how active a fighter has been. It is worked out fresh before every fight, so it can move between fights too, for example with age or a long layoff.

Classic Elo, shown next to it, is the results-only version. It reads more like normal rankings, and the Rankings page can be switched to it.
