Good article. I've used Anki for languages, but not so much for math. My personal go-to is maintaining libraries, which also offers spaced repetition (bugs should get less frequent over time), and iterative deepening as you need to go deeper into a domain to grow the library.https://twitter.com/wrong_less/status/1353100206141800449 …
Doing exactly this right now, though I read the text book to the end, for fear of missing appropriate concepts.
