hello,
can someone help me understand why do my card intervals become extremely long after i optimize the parameters for FSRS. for example a card that had an interval of 2 months becomes 1.3y after hitting good?
when i use fsrs with the default settings, it is way closer to the expected time i should see that card
i have 81k reviews total before using fsrs
I think FSRS is working as expected.
When I optimized FSRS parameters and selected “Reschedule cards on change”, some of my cards had longer due dates, but about 15% of them or so actually became overdue.
FSRS optimization is looking at your history with these cards and using to predict what your future with these cards will be. And FSRS intervals have a tendency to be longer than what you’re used to with SM-2 intervals. fsrs4anki/docs/tutorial.md at main · open-spaced-repetition/fsrs4anki · GitHub
the FSRS tutorial says this: “It’s worth mentioning that for mature cards, the opposite is true: FSRS is more conservative than SM-2.”
this is why i thought it was weird that all my mature cards that i was reviewing had huge intervals, so i switched back to the default parameters because i was more reasonable and was sure i will forget almost all of the cards i was reviewing before the interval that it gave me with the optimized parameters.
