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.

This is a follow-up to Do Filtered Decks have an effect on FSRS? and can probably be merged with that topic.
For a Filtered Deck with the Reschedule option disabled, do the review ratings affect future FSRS scheduling? (Because the Reschedule option is disabled, I know the review rating won’t affect immediate scheduling. However, I don’t know whether it might affect future rescheduling?)
My confusion is because of these statements:
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.
This says that grades are not recorded for Filtered Deck study and thus cannot be used by FSRS.
However, on the contrary, when I look at Card Info I see that grades are actually being recorded for Filtered Deck study:
Given that Filtered grades are recorded and do appear in the review log: Does FSRS use these recorded Filtered grades in its calculations, and does Filtered Deck study affect how a card will be rescheduled in the future?
When the reschedule option is disabled, FSRS doesn’t use those filtered reviews for any purpose.
BTW, I am curious: Why do some users want to do some reviews but not let the algorithm use them for scheduling further reviews? What’s the use case?
Hi im the original OP to that linked thread. My main use case for doing filtered reviews but not wanting it to affect scheduling for further reviews is simply cramming. I found that through my experiences that its hard for me to learn my x amount of new words a day within the normal Anki slot. Sure, I am successfully able to remember them after the 1 minute, and 10 minute scheduling before they get sent to the next day, but by that next day I found that I don’t remember half of them, sometimes more than half. This builds up and suddenly I have a huge stockpile of cards I don’t know everyday, so it feels like instead of 20 new cards per day its more like 40. This obviously is factored in by Anki’s FSRS parameters, but I still found it more inefficient for learning new cards per day by lowering the amount I can learn or just letting it stack and let FSRS do its thing, when I can just spend 5 minutes and cram the cards and learn them like I properly should.
By using filtered decks, I cram the new word/any forgotten words for today, which immensely helps me remember the new cards I learned for the next day, and the days following that.
It’s like in school I cram before an exam and I know everything I need to know before I take the test and then I do well. Then a day after the exam I remember nothing. Cramming to me is jump starting that learning process and then Anki is the method to keep that as longer retention learning. But perhaps this method is wrong, and I would like to hear feedback on this.
I wasn’t actually “doing reviews”. Instead, I was trying to use Filtered Decks for purposes unrelated to my regular memory and recall study. That is why I don’t want my Filtered Deck activity data to affect FSRS. Ideally, my Filtered Deck activity wouldn’t even be recorded.
Specificaly, I was trying to use Filtered Decks for language learning pronunciation and shadowing practice.
Using Filtered Decks was just a means to have Anki show me relevant cards in random order in exactly the same way that they would appear as if doing normal reviews. Pressing the “Good” or “Easy” button was just a means to be done with the current card and to advance to the next card.
It sounds like you have multiple pieces of information on a single card, and you only want to study some of them, and for the rest (like pronunciation) you want to “review” without actually reviewing.
But each note can create multiple cards, so why not have Pronunciation cards alongside your Meaning cards, and do actual reviews for all of them?
Some people use the preview mode for that. Not this preview mode, the one in browser. And I agree with you, it shouldn’t even record these in card info. But I guess it might still be useful if you want to have the stats in stats screen.
Its fine what you’re doing. I just think you should’ve been using the reschedule mode. Now you have extra reviews happening outside of FSRS’ purview that is affecting your memory state but FSRS would’ve no way to include that in.
You’re right, the way I worded that was confusing. (I don’t know if I was trying to recall from memory, or looking at an older version of Card Info.) Sorry about that!
Study in a Filtered deck without rescheduling does add an entry to the revlog. But it has a few key differences from a revlog that is used for rescheduling.
- The Type is “Filtered” instead of the state the card is in.
- The newly calculated Difficulty is recorded (in the Ease column).
- The Due date, Interval, Review counter, and FSRS memory state are updated in the top portion of the card.
Here are some screenshots so you can compare them –
Those Filtered grades are not used by FSRS to schedule this card now, or as review history during optimization later on.
It sounds that you should adjust your learning steps. For example, try increasing the 10 min step to 20 minutes or 30 minutes or whatever else you feel comfortable with.
