And while Wozniak thinks his complex algorithms help, he seems to be alone in this. It’s not even clear that expanding versus fixed intervals makes much of a difference.

I cite 3 studies which found that fixed intervals were better.

(If it’s not even clear that expanding is better, then surely it is not clear that SM2′s expanding is worse than SM6′s tweaks to SM2!)

It is definitely a modern tool for spaced repetition, which is a rather old (but oft ignored) idea.
