Idea : Allow Known threshold to be defined based on Stability (FSRS) instead of Intervals (DR-Specific)

[JSchoreels]

Hello,

I was wondering about what would you think about allowing people to use stability (prop:s) from a card instead of the interval for determining if they know or not something ?

The thing is, interval=stability when DR (Desired Retention)=90%, but stability is DR independent while interval is. Which means right now, if an user has some deck at 70% DR and others at 95% DR, then AnkiMorphs would consider the cards with 20d interval as being known wether they come from the 70% DR or 95% DR preset.

If you think it's a good idea but don't have time, I could take a look to create a PR when I have some on my own.

Is desired retention a deck specific setting, or global? Ankimorphs doesn't handle decks, nor use any deck info.

It's a deck specific thing, but you don't need it for the known threshold, because the stability is stored inside the card_info. This is also why using Stability can be quite easy and more reliable than interval (which need to be interpreted)

I checked the code I think you get card infos from the DB directly, so something like

SELECT json_extract(data, '$.s') AS s FROM cards; should do the trick to get stability

Ah, I see, you can do stuff like this:

    card_id = CardId(1673815538720)
    card = mw.col.get_card(card_id)
    print(card.memory_state.stability)

feel free to work on a pr 👍
