FSRS impact of moving cards

Anki FSRS

How does moving a card to another deck impact the way FSRS deals with this card?

It doesn’t – necessarily. But if you move it to a deck that uses a different Deck Options preset, then –

  1. When you study or reschedule that card, it will use the FSRS parameters and desired retention of the new preset you just moved it to.
  2. Until you re-optimize the old preset, the parameters there will still include the history of that card.
  3. Until you re-optimize the new preset, the parameters there will not include the history of that card.

It’ll also affect sorting and searching by difficulty, retreivability, stability. Cards moved a different deck don’t have their memory state preserved and they’re recalculated only when you study them or optimise the new preset.

How would they be recalculated when you study them if they don’t retain their memory state?

I think that was fixed a while ago
@L.M.Sherlock I believe in the latest version of Anki memory states are recalculated when moving cards between decks that are under different presets

No, I tested before making that comment.

This is still an issue:

Looks like it’s currently reset as @sorata said

EDIT: Ah, the memory state is recalculated when answering, but if simulated beforehand, a hardcoded default state is used

If you have the history and memory state is missing FSRS recalculates them.
