fsrs4anki-helper VS free-spaced-repetition-scheduler

You can set easy days via the FSRS4Anki Helper add-on: https://ankiweb.net/shared/info/759844606

And it also supports to postpone your backlog.

What was your retention before, using the old algorithm? If you don't know, download the Helper add-on, Shift + Left Mouse Click on Stats and look at the True Retention table. Make sure to select "Deck life" at the bottom of the window.

FSRS4Anki Helper (https://ankiweb.net/shared/info/759844606)

FSRS4Anki Helper is definitely the most popular Free add-on for Anki in recently. The author has researched and written a paper on spaced repetition and can customize Anki's schedule to optimize it for learning.

It's better to think about the mature card hit-rate you're aiming for. Most people will aim for about 90% hit rate on mature cards. There are some schedulers that let you play around with the goal hit-rate - IIRC, this one does that: https://ankiweb.net/shared/info/759844606. If you set a higher required mature hit-rate on a scheduler like this you'll see your cards more, which is what you seem to want.

I let my due cards build up sometimes, and my strategy when I come back is to sort them by lowest interval because I figure those are highest priority. I think the fsrs4anki-helper add on also has a reschedule function that might work for you, although I've never used it.

There is a patch now that ignores all notes with more than 10 cards: https://github.com/open-spaced-repetition/fsrs4anki-helper/issues/111

Use FSRS4Anki with FSRS4Anki Helper add-on. It has an option to set "Free Days" and then it's not scheduling cards on the days of the week you choose.

I'm not sure I believe we understand our own learning/memory anything like enough for this not to be total pseudoscience? Reminds me of A Beautiful Mind.

Libraries: https://github.com/open-spaced-repetition/free-spaced-repeti...

All are MIT licensed I believe, Anki is primarily AGPL

Just read the wiki ¯\_(ツ)_/¯

Also, sorry for nitpicking, but I just checked the code here, and I saw that you changed the formula for post-lapse stability, but you didn't update the formula in the description here.

I have another one, also about difficulty. Look at the long "Stability updating formula after successful review" formula, there is a term D-b. This seems very counter-intuitive. A large value of D corresponds to an easy card, but thanks to that formula it will produce a very small change in stability. A small value of D corresponds to a difficult card, but according to that formula it will change stability a lot.

So I checked this and it seems that there's a whole bunch of different parameters (initial difficulty, initial stability, etc), and a lot of them are constant. So the next step would be to use some kind of optimization algorithm, like gradient descent, to optimize those parameters based on user's review history, right?
