Average sequence of review intervals

Anki FSRS
1

hello,

I know FSRS makes things a bit more complex but does someone know what the average sequence of review intervals is if I hit good all the time with a desired retention of 90%. as a general rule of course.

first review: around 4 days ?
second review: around 15 days ?
third review: around 3 months ?
fourth review: around 1 year ?
fifth review: around 3 years ?
sixth review: around 10 years ?

even better if someone knows how incrementing the desired retention rate (go to 91, 92, 93…) influence the intervals.

thank you very much.

There is no “average” or “general rule” – it depends on your parameters and desired retention.

You can use tools like the FSRS Visualizer – Anki FSRS Visualizer – or the FSRS Previewer – Fsrs4anki Previewer - a Hugging Face Space by open-spaced-repetition – with your own parameters to see what intervals you would get with a certain series of grades.

Anki will tell you that in your Deck Options when you set a different DR.
