The polls seem to be unanimous on FSRS being better than SM2. The concern I have is why it’s not set as the default option if it’s so good?

Scheduler will only schedule your cards. SM2 scheduling isn’t particularly good anyways, so why fear about being “safe”? I personally don’t believe everyone should use FSRS. If you like ~30% less workload then FSRS is pretty good. But for me it has been a huge boon to my Kanji writing deck as I fail a lot of cards there. SM2’s new interval after lapse will always be bad and FSRS is just better at giving me good intervals after a lapse occurs.

It will likely become the default in the future, but for that automatic optimization is 100% required. With automatic optimization, users will never have to worry about tweaking any settings (other than desired retention) or clicking any buttons. They would be able to just let the algorithm do ithe job in the background.

It’s still pretty new. Transition to a new default, done responsibly, shouldn’t happen overnight. For a point of comparison – the v3 scheduler was introduced in mid-2021. It didn’t become the default until support for the v2 scheduler ended in late-2023, over 2 years later. I’m not saying FSRS is on that same trajectory, but it’s only been built-in for about 7 months.

Yes. Follow this link. I found his article through this. But actually he doesn’t say anything about FSRS here. Maybe because he changed his mind or because others used to think he’s trolling. If you want to contact him for some reason join the TMW discord server and search his name. Pretty sure he’s still there.

[image] sorata: discord server It’s probably best not to advertise discord here because it’s proven to be malware. Additionally, such servers are prone to be filled with misleading information. If you’re looking for a japanese learning community, the best option would be to join the DJT chats, you can access them with free software.

[image] slabz: why it’s not set as the default option if it’s so good? I can’t say for all fields of study, but in AJATT, we still refrain from recommending FSRS. One of the reason is that it’s a new thing that didn’t exist until just recently, and it hasn’t been proven enough to trust it. But people have lost their data because of it so I usually suggest waiting until it’s fixed (or use backups). Another reason is that it’s very complicated. You can explain how Anki algorithm works in one formula (new interval = old interval * ease factor * interval modifier), but FSRS apparently uses a lot of parameters and hasn’t been explained thoroughly enough. Of course, you can study the source code if you can, but most users won’t do it.

Not a fan of TMW either. I actually use discord through my browser. Is that still very risky? Also a bit personal maybe, why are you so concerned about such things? I sometimes feel like government agencies may be tracking you or something lol.

Should everyone switch to FSRS?
