Personaly i thinks its stupid, i was helping do a demo at a very commercial club the other day, and there were a few black belts, then i found out their criteria for being a black belt and all you had to do was be apart of the club for 12months and you were given it, nevermind how good your technicle ability is, when people are given these belts with out deserving them i have these people are generally quite cocky but have no technical skill what so ever, at this club the black belts hadn't even heard of pressure points, and there striking wasn't even that good, so if they were attacked they may feel they have a chance but they won't because their fighting ability isn't very good.
