Flashcard review workload model outputs
Modelled daily flashcard review loads for eight new-card rates (5 to 100 new cards per day) at 85%, 90% and 95% target retention, after 7, 30, 90, 180 and 365 days and at steady state. 24 rows, one CSV (flashcard-workload-model.csv).
Limits
These are outputs of a stated interval ladder, not observed learner data. Lapses are not modelled and real schedulers adapt intervals per card.
