Nice write-up! Haven't tried SRS yes, I definitely see how it can work well for learning facts like you show. For fuzzier subjects like history or psychology, I've had some success with writing questions for myself that require more of an understanding of the subject than mere facts. (Never got to the repetition part, though.) I found that writing non-trivial questions also helped me understand the subject matter better. How would you work with such subjects?
