When considering upsets for the list, we took the winner’s rating at the first of that month and divided it by the loser’s rating at the first of that month. The list is sorted by the loser’s rating in descending order and we limited it to fights where the losing fighter’s rating was equal to or more than 3 times greater than the winner’s. Fighters coming back from inactivity are excluded from the list as they did not have a current rating.
