That sounds like a pretty good idea. From now on, I'll take detailed notes of my judo classes. It will be fun to watch my progression from that perspective.
I am surprised that it didn't work for you. When I used to do Xing Yi, I found that if I had to think about the move in a way that I usually didn't (like writing it down), I developed a greater understanding of it. But maybe your learning style theory is valid too.
