FSRS Help Me Decide DR - based on daily time

[szalejot]

I am playing with the new Help Me Decide option for desired retention calculation.

For me, it will be useful to set how much time daily I can spend on Anki, not how many reviews I will make.

I am not sure how many reviews I will be able to do daily, but I have a steady schedule of how much time I can dedicate to Anki each day. So in reality, the question I am trying to answer is: If I know that I am able to do X minutes of Anki daily, what desired retention and new cards a day should I set to maximize the number of memorized cards after Y days.

@L.M.Sherlock @A_Blokee this is something that shouldn’t be difficult to implement. In fact, the Python version already has a variable for that: fsrs-optimizer/src/fsrs_optimizer/fsrs_simulator.py at 221e4a901d1ddff0a204085b22d9fe2ed48031e7 · open-spaced-repetition/fsrs-optimizer · GitHub
The simulator will also need a “New cards first or reviews first” setting. If there are no limits, then it doesn’t matter. But if there are limits, it could lead to different results: the user being able to learn new cards but not to review old cards, or vice versa.

Maybe you could use the point at which the the DR and the time you want to spend intersect? Orange here is with 10 new cards/day blue is with 0.

src/simulation.rs

It is implemented already but not in Anki.
