Idk about MMA, but afaik his kickboxing record was pretty good, but essentially he was an average/slightly above average pro who had a massively padded record - he mainly fought people who were ranked far lower than him, won some low to mid level titles and didn’t take actual fair matchups or compete in tournaments that you’d expect actual highly ranked pros would compete in.

So, he was a perfectly adequate kickboxer and could beat a lot of pro kickboxers in lower divisions but nowhere near “best in the world” / “olympic level” or whatever else he claims
