```auto (put here) AnkiDroid Version = 2.20.0 (d41d16a45c00b0bdbd3b13ac988143db5ef8ae90) ``` Hi, I couldn’t say everything I needed to in the title, but I’ve recently just tampered with my settings in the advanced Maximum interval 36500 Historical retention 0.83 Ignore cards reviewed before 16/05/2025 Because around that time I completely changed my way of doing anki cards, started using fsrs and everything. But when I optimise fsrs it says” ⁨1,147⁩ reviews” beneath it. And I’ve done my than that today alone. Ever since 16/05/2025 I’ve been doing like roughly 2,000 a day. With my desired retention at 0.95, but I want to lower it to 0.90. Just in the last three months for my main deck it says I’ve done “⁨245,868⁩ reviews” And if I just use the default settings for advanced Maximum interval 36500 Historical retention 0.90 Ignore cards reviewed before 01/01/1970 And click optimise then it shows” ⁨1,163,460⁩ reviews” Which roughly alligns to how many reviews Ive done for that deck 1,126,686⁩. So what I want to know is why is it only saying only ⁨1,147⁩ reviews. I have really bad memory if you can tell. Thanks for reading this far and I’d appreciate any help given. ---

Thanks for the response man, sorry to ask the obvious, but just wanted to make it clear that you mean any cards that I’ve reviewed before 16/05/2025 get ignored even if I’ve reviewed them after that date? If so that does make sense. And assuming that’s the case, should I optimise ignoring any cards before 16/05/2025 or add more cards regularly and then do it. Because 1,000 cards sounds like too little data to go on. I’ve already gone down from 0.95 desired retention to 0.90 and optimised that with default advanced settings. And I can just stick with that for a while and see if that helps. Because I’ve not been doing any new cards at all and am still stuck at 2,000 + cards a day. Because I was never seeing any reduce in amount in my cards for the past 6 months. Thanks for the help again. ---

That’s not 1000 _cards_ FSRS is considering – that’s 1000 _reps_ it’s considering, likely on much fewer than 1000 cards. It’s how many cards you’ve introduced _after_ that date. You’re right, that’s not very much review history. > [@BeybladerAshKetchum](#): > > Because around that time I completely changed my way of doing anki cards, started using fsrs and everything. Ignore-before is a pretty extreme solution for handling some specific situations. What makes you think it’s necessary in your case? Simply enabling FSRS isn’t enough, or else we’d all have to use it! Were you grading your cards inaccurately? Were you mis-using Hard for answers you actually got wrong? > [@BeybladerAshKetchum](#): > > I’ve already gone down from 0.95 desired retention to 0.90 Your DR isn’t part of optimization – but 95% DR is too high for most users, especially if that’s a lot higher than your actual retention results. ---

Hey there, yeah I had before that been not fully trying to recall meaning (I do japanese vocab cards and try to recall the meaning and prounounication) of the cards and just passed if the meaning was roughly the same, of course this wasn’t for all cards but for a big chunk of them. I have cards that I’ve reviewed over 100 times and still don’t remember. Also when I was starting out I kinda abused hard button for a short while, but not long in terms of total amount of time on anki. These 6 months have been quite long, double the time I spended usually” 2,000+ 2+ hours everyday “ (and because of that I never could do new cards otherwise I’d be spending alot more time in anki that’s why there’s only 1000+ cards introduced since 6 months ago), so hopefully It’s more than enough to essentially ignore those reviews. (Yeah probably not I’d have to maybe another half a year like this before those reviews become a high percentage of my total amount of reviews done.) Thanks again. ---
