Point of clarification: I'm not arguing against time-in-grade. I'm just doing a sort of reverse devil's advocate. I'm asking the question to see how others will answer. What is the reason for time-in-grade requirements prior to a belt promotion? If you have proven competent enough to move up, but you have not yet been at your current rank for long enough, what is to be gained by staying at this rank for an extended period of time? For example, if there is a 2 year minimum from 1st degree to 2nd degree, and I can manage all of the following in 6 months, what is to be gained for staying 1st degree for the next 18 months? Memorize the forms and any other curriculum material Demonstrate techniques better than anyone at 1st degree and comparable to those at 2nd degree Win more matches than I lose against 1st degree black belts and hold my own against 2nd degree If I can show my understanding of the curriculum, my knowledge of the techniques, and my ability to apply them competently, what do I gain by not gaining rank?
