That's really interesting, I'll have to give supermemo a try. I definitely remember those items in WaniKani; a lot of the times they were mnemonics based on pop culture references that I just didn't get, or the mnemonic was just kind of a stretch, or too many similar concepts had been introduced at once. When I stopped I had definitely hit a wall where I just didn't feel like I could keep learning.
