BJJ and their ranking is something I mentioned earlier. I commented how long it takes to reach black, yet nobody seems to care or complain. When the rank happens, it happens. They might have a youth belt system, I really don't know. Either way, I also asked what the rush was, with some people, in other arts, with ranking. Almost seems like if someone starts at a certain age, it's almost expected that at specific intervals a test will happen, and you can pretty much expect a BB by a certain time. IMHO, the time frames are simply a guide. People hear it takes 2mo to go from white to yellow and dammit, at that 2mo mark, you better get tested.
As for the TKD...well, I should probably not comment or think before I speak.
LOL! That is an excellent example though, of the black eye that art gives.
