Out of 40 matches, 15 of them against top 10 ranked opponents, 21 were in the top 25. 25 were in the top 50. Fedor was 13-2 against top 10 opponents. He faced against 13 former champions in from different organizations, going 11-2 against them. 9 were former/current kick-boxers, 13 were wrestlers and 11 Jiu Jitsu submission fighters. 7 Miscellaneous. He faced a top ten opponent every 1.5 years from 2001 to 2011. Add to the fact he went undefeated for ten years as well.
Ok.
But use original rankings from that time, not this Fightmatrix that are generated 15 years later.
Fedor has 13 + 1 top 10 wins by original rankings from those historic times + more good wins that were not ranked like Coleman 2, Arona, Goodridge, Haseman, Monson, Rizzo.
