FSRS has no model for “short”-term (intraday, sub-1d) memory. No, it is not recommended that you leave your learning/relearning steps empty.
Clarifications about FSRS-5, short-term memory and learning steps – Jarrett Ye
TL;DR:
Key Takeaways
- FSRS-5 primarily models long-term memory but considers the impact of short-term reviews on long-term retention.
- Short-term reviews significantly affect short-term memory, but modeling this is complex and a comprehensive short-term memory model is not yet available.
- In Anki, if you previously had non-blank learning steps, it’s not recommended to switch to blank steps when using FSRS. Maintaining appropriate learning steps is still important.
- FSRS Helper can recommend learning step settings based on personal statistics, offering a data-driven optimization approach.
