This was one of the biggest issues for me, for a while, and part of the reason it took me over a decade to get to black belt. I knew (and still know) all the techniques from my original art, up to black, which is probably 75+ separate techniques not including forms. My issue is that then we also needed to know which techniques were for which belt, and what order they were for that belt. I just flat out could not remember the order, especially since I learned many of them out of order to begin with. So you could ask me to perform a technique, any technique, and I would do it better than some of the black belts (whom had been training half as long as me), but then you say "perform brown belt 1 kempo 3" and I'd just give a blank stare and start laughing that you want me to remember what that is.
