those ranks are bullshit. at best hes a 3rd degree bb. Next year or two he will be a 6th? along with legends like Renzo and Jean Jacques? Jean Jacques is around 40, got his BB at age 18/19, was Gracie Barra instructor and has about 16 years teaching in the US alone and he is still a 6th degree BB.
To customers, if they see the Gracie Jiu Jitsu + 5th degree BB they will never question it... to customers. Marcelo Garcia needs to learn from these fast promoting black belts because hes obviously been doing something wrong.
