FSRS>=5 is a significant regression for a minority of users who use again a lot on new and learn cards

[7Gamil]

Why we not implement simple solutions until we figure out how to let everything to FSRS?

e.g., with toggle option if needed:

1. Back the use of learning steps (no effect by FSRS until in review state)
2. Auto reset after change card state from learn to review
3. Add 0.0250 to difficulty parameter, this worked well with me until now using Anki 25.02

@7Gamil

I also tried adding 0.0250 to the difficulty (multiplier) parameter 8 for a while now, and the cards return to normal difficulty faster than usual, so the intervals are increased as well. It seems to affect only cards with high difficulty, and for cards with low difficulty there isn’t a difference, and this is perfect. I will continue with this option for now.

FSRS doesn’t use stuff like “New” or “Learn” internally, only interval lengths and grades. I’ll try using a new parameter, and I’ll also try not updating D at all if the interval is short; though I doubt that the former will result in an improvement and I really doubt that the latter will result in an improvement.

I believe, It can be done through custom scheduling to let FRSR only effect review cards as I said here

@7Gamil

Maybe there is a better way if we used FSRS through custom scheduling, as the script said:
// FSRS only modifies the long-term scheduling. So (re)learning steps in deck options work as usual.
I tested it, and it seems to me it’s not affecting the learning cards.

You can always get the latest version of FSRS scheduling from here and follow this tutorial to set it up through custom scheduling.

You can also use the built-in optimizer to get optimized parameters and update them in the script. Then, disable FSRS built-in to make sure the custom FSRS is the only one working
