I read through the Anki code, and there’s a bunch of logic which reschedules cards largely based on the user’s first review: [image] The problem comes when you ignore reviews before a certain date in the options. Case in point below. In this deck, I have ignored all reviews before 1/1/2022. It is…

[image] tequa1: In this deck, I have ignored all reviews before 1/1/2022. It is thus treating the first review interval as the the 5/1/2022 one, with an interval of 8.11 years, and rescheduling based on that. I’m pretty sure this isn’t the case. The card is completely ignored if it had been r…

That is true when optimizing parameters. My topic though concerns force rescheduling of the cards (either through pressing “Update memory state and reschedule” or having “reschedule cards on change” on in the options). It uses the “starting state” as the first review after the ignore date. I have de…

I’ll note that I’ve been able to workaround this by optimizing parameters with the ignore date set, then resetting the ignore date back to 1970 and then force updating the cards. Not ideal though.

I don’t know the code that well, but it’s calling “compute_memory_state” in memory_state.rs, and passing in “ignore_revlogs_before_ms_from_config(&config)” to “single_card_revlog_to_item” when it shouldn’t be pub fn compute_memory_state(&mut self, card_id: CardId) -> Result<ComputeMemoryStateRespo…

[image] Anki 24.10 Beta Beta Testing Is it a problem? It’s intended: Please see the section “Ease Factor to Difficulty”.

I’m sorry, I can’t find the “Ease Factor to Difficulty” section in the manual if that’s what you’re talking about. Could you link me? Edit: I found what you’re talking about and it doesn’t seem to address anything about the “ignore reviews before date” option, which is causing this bug Unless I’m m…

@L.M.Sherlock How does this sound to you?

I’m actually having this problem as well. Was there any resolution in 25.02 for this?

@L.M.Sherlock Is this expected behavior with an “ignore cards reviewed before” date?

I think this should be fixed? Clear memory states during bulk action if item is None main ← user1823:patch-1 opened 01:30PM - 11 Jan 25 UTC (UTC) [image] …
