Iteration cadence for spaced repetition experiments

expect iteration time of 3-4 months: that's how long it takes to start to really forget things you've read about, which is when you can start to actually see what you retained vs what you didn't, so that you can change how you do things. but 3-4 months is only if you come back to review things to see what you've retained. if you don't use things, it could be much longer until you realize you've forgotten things. luckily, with anki, if you put in some low-effort cards, you will be forced to review something in the 3-4 month time period, where you get to see what you retained. this is how i found out that i wasn't retaining some things in analysis, which is how i eventually figured out i needed to put in problems to solve.
