For my srs system, I’ve set my maximum unlearned to 30 cards. On the first day, I got two of them correct so their scores got bumped up to 400 and 300. The learned threshold is 1600, and my PPD is 100. On the second day, the test only gave me 28 cards to learn. How do I set the test to have 30 cards each day while maintaining an SRS system? Like if a card isn’t due for review, put another card in its place? Or does this happen automatically if any card crosses the learner threshold?
