Two books that I often recommend on learning are: The ABCs of How We Learn by Schwartz, Tsang, and Blair (https://bookshop.org/a/91541/97803937...) and Make It Stick by Brown, Roediger, and McDaniel (https://bookshop.org/a/91541/97806747....

Supermemo advocates for an expanding spacing schedule, which isn’t necessarily bad. But the question of whether fixed or expanding intervals are superior is complicated. Perhaps it has something to do with how hard the retrieval is or the number of retrieval attempts. But there’s not a clear winner. See these two pieces for further discussion.
