Glad to hear you had a good training session.
I'm not sure what Mr. Stanton's credentials are as "number 1 Muay Thai fighter in the world." I found some references to him being a IMTKA world champion, but I've been unable to find any details regarding the IMTKA itself. Does it stand for International Muay Thai Kickboxing Association, maybe? Anyway, if it was one of the more prestigious sanctioning bodies I would expect to be able to find some information online regarding it.
If I was going to award the title of "number 1 Muay Thai fighter in the world", I would probably look at the list of winners of multiple Lumpinee stadium or K1 championships.
