| I think the belt structure depends upon how the instructor chooses to market his school. Most of the time they add grades that dont exist for money purposes, essentially to generate more revenue.
If you look at Korea, North (pyongyang) or south, there grade structure is simple and is followed coherently. You dont see obscure grades such as orange or half black because it is not possible and doesnt follow any philosophy taught by gen choi.
All the schools I have attended (ITF) have followed 10kup - 1kup with the belt structure being white, yellow green blue red and black with a tag in between. Essentially making a belt the equivalent of progressing 2 kups or grades. |
