Hi so I use filtered decks a lot to review forgotten cards, and I notice that the Learning/Young/Mature statistics change based on the answers I input in them. Does this affect my FSRS evaluation/optimization? If so, how can I prevent it?
If you have reschedule turned on in the filtered deck, it’ll affect your scheduling outside of the filtered deck too. Turning that option off will make cards in filtered deck appear in a “preview mode” and grades from here wouldn’t carry over to your home deck. See Filtered Decks - Anki Manual.
By default, Anki will return cards to their home decks with altered scheduling, based on your performance in the filtered deck.
To change this behaviour, turn off Reschedule cards based on my answers. When this is turned off, cards are shown in a simple “preview mode”, and when they are returned to their original deck, they are returned exactly as they started.
I have Reschedule turned off, and yet it still carries the grades over. For example, when I press Good to a Learning card and then delete the Custom deck, it increases the times answered for Good by one on the deck statistic.
I don’t think it reschedules the card, but it does change the card answered statistic. My question is really if the statistic of answering Again/Hard/Easy/Good changes how FSRS evaluates and optimizes when you want to update the FSRS.
I don’t think filtered reviews are used in FSRS.
You can look at the Card Info for the card and see that no grade was recorded and the scheduling of the card did not change. If it’s not in the review log, FSRS can’t use it for optimization.
