A lot of the earliers generations' wins are discounted by acannxr because, although they were fights between two ranked HWs, they took place in "open weight" tournaments. Why that makes a difference? I have no idea. But that's why Sobral wasn't included. I also think he made quite a few mistakes due to this qualifier, as he has removed some peoples wins and missed others. For example, I already pointed out to him that he didn't realize that 3 of Barnett's wins came in "open weight" and I'm sure there are more. But that means guys like Werdum, Overeem, Nogueira, Fedor, Couture, Barnett, Randleman, and Coleman had names omitted from they're listed because early UFC, PRIDE, Rings, and Pancrease had a lot of fights take place at "open weight".
Or...because that would tie Fedor at 66 with Stipe (you should check your math on Fedor's total, it should be 62). Which would mean Fedor has the same total in your arbitrary point system and nearly double the quality wins of Stipe.
