As I understand it, Chuck Norris also integrated it into his system. I haven't spoken to anyone in his organization (CFAF?) for a while nor seen the Wiki, but I'd heard Machado BJJ had been required training once you hit a certain rank.
We're in the West San Fernando Valley in Los Angeles, and we're surrounded by schools run by former Chuck Norris students or their students, most of whom are not affiliated with Chuck's organization.
Coincidentally, I saw Pops Krasnoo today, and if I remember correctly, his old school, Sherman Oaks Karate, was owned by Chuck Norris decades ago. Something like that anyway. We talked about cars, not martial arts.
