For some fights, I believe that the record should include both KO and TKO categories, as they could provide good levels of competition, sans some fights such as Mike Tyson, where you would just have to stall to KO instead of TKO or King Hippo, where a TKO is obviously impossible

Prolonging a fight to go for either a KO or TKO usually ends up reducing the skill needed and relevant RNG needed in comparison to whatever happens to be the normal fastest way.

Ok, that makes sense.
