Hello
I just switched from Anki 24.11 to 25.2 and noticed the FSRS simulator under deck options giving me pretty substantially different results now. For example, I have a deck with no more new cards, a solid retention > 80%, and currently ~150 reviews/day. With no new cards I was expecting my reviews to drop over time, and indeed the old simulator gave me this:
Now I ran the same simulator for the newest Anki and it suddenly looks like this:
I did not re-optimize or change the fsrs parameters or any of the deck options. As you can see, reviews are no longer expected to decrease over time and now I don’t know which result to believe. Is there any reason for why results might be so different, i.e. were there any significant changes to the simulator? I kind of think that the old result looked more reasonable, as I was expecting (or hoping for) reviews to come down over time.
