to add to this, I think spaced repetition is to learning, the way typing speed is to programming. It's good at solving for the minor frustrations and slowdowns that stand in between you & the complex reasoning to get to a solution. When I can edit code via vim keybindings quickly, I can move things, sketch ideas, swap entire blocks, and so on, easily. That lets me check and look at things, and allow my whole brain to be spent on higher level things like looking at the control flow, applying aesthetic considerations to simplify, or whatever. I failed Calc 3 as a college freshman because I had taken high school calc as a junior, leaving a full year between. I understood the ideas of calc 3, but couldn't remember the basic stuff like integrating tan() or whatever. (and I also didn't have any study discipline at the time to actually solve for my situation). So I couldn't answer the questions on a test even though I knew the steps I would need to take past a roadblock. Solvable with study, which would have been effective in the form of spaced repetition flash cards.
