Rickson Gracie BJJ Blue belt requirements (mindmap link)
Looks like this is from a guy who is just an affiliate with rickson.
Honestly I could not ever take that chart seriously. If I didnt know anybetter I would say Louis Parnes is the co-owner.
I posted it mainly because of the interest in the mind map idea. I thought about making a mind map and then realized just how much time that would take... If I'm not mistaken there is a pretty good Pedro Sauer mind map roaming around but I can't seem to find it anymore - I saw it about 6 months ago.
