water down, like add extra belts because people dont have the patience?
that's the assumption some people have. i can't say that's my professor's.. i'll ask him or one of the others next time i train and let you know what they say.
but even if it is to keep someone hanging on a little longer for a few more bucks eventually someone who doesnt love the sport for grappling and is only hanging in for a new belt will quit anyway.
something i said in a previous post i'll bring up again... i've been to three belt tests so far and every time it's the same thing:
-40 or so white belts test for green--- all of them make it
-8 or so green belts test for blue--- not all of them make it
so yeah you can say green is an artificial belt midway between blue intended to keep students interested but i think it actually does the opposite. they get that new shiny belt but still somewhere in the second half of training to bleu come to the realization BJJ isn't for them and over 75% of the people who stuck it out to green end up quitting before blue anyway.
thinking of those numbers the number of people going for purple and brown usually is around 4 so it really says a lot about BJJ attrition rate. i don't think the lack of belts is the problem... although i really hope they get with the program and add a belts with stripes... all these solid colors wreck my figure while im grappling.
