How reviews and difficulty work
Each skill starts with friendly numbers. Three comfortable reviews on different days unlock larger numbers; three more at that level unlock decimals. Older levels remain in review.
Comfortable reviews are spaced by 1, 3, 7, 14, 30, then 60 days. “Got it, slowly” brings a review back tomorrow. “Missed it” gives you a fresh question from that skill after two other answers, or sooner if nothing else is due. Retries can extend a round beyond ten questions. Extra practice on the same day cannot fast-forward progress.
This is a simple practice schedule, not Anki’s FSRS. Days are counted in UTC. Progress saves to your server after each rating.
