Fighter Elo
The rating the forecasts are built on. It projects fighters.
Classic Elo only moves on wins and losses, so it reads more like normal rankings.
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.
