I look forward to giving user feedback when I’m able to signup. > our Humane Spaced repeition system. Based off of the popular FSRS, our Spaced Repeition System will adapt to your review style. Take a few weeks off? No problem. Want to study ahead one day? No problem. Took a 2 year vacation? We're jealous, but we've got you covered. I really resonate with this. I find that after a long break, I have forgotten a lot less than Anki’s algorithm believes. Is there some reasonably scientific reference for this? I mean, I’d be interested to read someone’s study or theories here.

Well for one thing, Anki is using an ancient SuperMemo algorithm. I wouldn’t take Anki as a benchmark in terms of spaced repetition effectiveness.

  anki doesn't use the ancient sm algo anymore anki uses fsrs but afaik it still "punishes" you for taking breaks

    It does still use SM2 by default -- you have to turn on FSRS manually. https://docs.ankiweb.net/deck-options.html#fsrs https://docs.ankiweb.net/deck-options.html#fsrs

    You can set easy days via the FSRS4Anki Helper add-on: https://ankiweb.net/shared/info/759844606 https://ankiweb.net/shared/info/759844606 And it also supports to postpone your backlog.

    As others pointed out, SM-2 is apparently still the default. FSRS would indeed be more interesting, as it seems to be heavily “inspired” by SM-18.

I know Anki uses a modified version of SM2 so I can't say for certain, but if I recall correctly they are still using a linear algorithm. Most forgetting curves are, well, curved. More logarithmic. Once you go too far away from the 'due date', the algorithms decent quickly to "0% chance of recall", where in actual memory it's more similar to a half-life. It's been a couple years though since I've worked with that algorithm

FSRS has been available in Anki via extensions for more than a year, and recently landed natively. It can be enabled in deck settings with a toggle. https://docs.ankiweb.net/deck-options.html#fsrs https://docs.ankiweb.net/deck-options.html#fsrs
