us ps2 evo rankings

does anyone know the complete ranking system for quest mode? if someone could post a list, that would be great /versus/images/graemlins/smile.gif

and also, does anyone know the requirements for promotion for each rank? i'm currently at hero rank with akira, and i'd like to know how many more of these ranking matches i'll have to avoid demotion in to get to champion.
