fading
strong
lessons fade as days pass. a short review brings them back and pushes the next one further out.
nothing to review yetfinish a lesson first. it shows up here as it starts to fade.
how it works
review uses fsrs, a spaced repetition schedule like the one anki uses. after each review it works out the next gap from your score. easy lessons wait longer, hard ones come back sooner. holds N days is how long until you would likely remember it less than nine times in ten.
