Anki is set up with a long review cycle (1 day, 1 week, 1 month, then automated) and I sit down to do my reviews about once a week. In that process, I usually end up having new ideas to make notes about based on either the randomized order the notes show up in or spotting a connection between the review note and something I've been working on lately.
[1] In practice, I let many/most of these go unrecorded - I probably average about one new note per day, but in bursts.
* Learning biology, memorize terms like "anabolic reaction" or "reverse transcriptase"
* Learning algebra, memorize major groups like S_n or GL_n
* Learning statistics, memorize the major probability distributions, their means, and standard deviations
* Preparing for math contests, remember things like "Chinese remainder theorem"
That's a tiny part of learning, but it dramatically accelerates the other parts. At that point, when you're working through texts, you'll understand what you're reading without looking things up or thinking about it. And when you're engage in complex problemsolving, you'll have the knowledge ready.
Do this either on or before the first (surface learning) pass, and once they're memorized, use them in more advanced contexts (e.g. reading research papers, teaching, complex problemsolving, etc.).
All this stuff interconnects, and SR gives a fast, cheap way to start building out the simpler parts of the knowledge network.
Seeing this did make me wonder how I might be able to get better at memorising important parts of iso/iec standards at work, but I can't see how that maps to flashcards
But of course it's possible that you almost never need the same information twice, in which case committing it to memory wouldn't be particularly useful.
Mixing the questions between both pools and studying as a unit I've found has had two great benefits: 1) I'm not focusing on Technician first and then going for General as a "bonus" and 2) it helps me see the connections between the material.
