And I would really question the integrity aspect anyway.These are the same people who have ripped tons of people off with metamoris. Also probably the biggest cult in bjj, I posted a few months back about the current blackbelt who was brainwashed by them and talking about how Sean Roberts was strangling him again and again as he was telling himself in his head that he wasn't as good as he was because he didn't know the true Gracie jiu jitsu or whatever LOL.
Read the message board threads/reddit, there are Royce Gracie/Valente Bros, etc. black belts in the vicinity of these Gracie CTCs. You will randomly see online blues come on and say "if I want myself or my children to win medals I would go to that Royce Gracie black belt...but if I want to learn true self defense, I would send them to <16 year old karate girl>". People actually believe stuff like this.
edit: I had forgotten details from the account of the former Gracie student, current blackbelt, here is that post:
