Spaced repetition schedules a review just before the forgetting curve would drop the trace — Ebbinghaus mapped that curve in 1885; Cepeda and colleagues later measured expanding gaps in live learners.
This atlas ranks it near the top for evidence, exam fit and long retention, and middling for first-week speed — early hours go to card design.
Use it as a calendar for facts you must still name in six months — not as a substitute for a blank-page problem.
