It's _kind of_ possible. https://www.desmos.com/calculator/9pbylwb5yu  See how R falls much faster if the function is exponential? You may be surprised what happens if we zoom in to the beginning,...

New idea: only reschedule cards if at least one of these two conditions is met: 1) The new interval is different from the last one by more than 5%. Rationale:...

As I said on Discord, in this benchmark RMSE is calculated in a very specific way. I suggest getting the values from here: https://github.com/open-spaced-repetition/srs-benchmark/blob/main/result/FSRS-6-recency.jsonl

I don't think that's possible 1) As far as I know, in Anki we can't access the card creation date during optimization anyway 2) Even if we can do 1,...

Oh, so cid is a unix timestamp? Interesting, I didn't know that. I don't understand your suggestion, though. Wouldn't that result in having to calculate tons of S0's for every...

> Yes, but after that, we can try to find a curve that fits most of them. Can you write some Python code or pseudocode to make it easier to...

Alright, but I still don't think that this is better than just calculating S0 the way it's done right now.

Honestly, I highly doubt it will be worth it, and it will probably be very difficult to figure out how to calculate the new S0. So unless Jarrett wants to...
