FSRS Desired Retention Simulator

I haven’t seen anything about this addition to the 26 version in the forum.
basically, how do I read the curve in the simulator and how can it help me decide what the best desired retention rate is ?
thank you !

Start here: Deck Options - Anki Manual .

That feature generates a personalized, interactive version of the graph pictured here: Deck Options - Anki Manual .

Actually, the graph has been inverted in one of the recent versions. Now, the higher the more efficient.

I don’t know what you mean by that. Say more? Which graph has been inverted?

The “Time / Memorized Ratio” graph has been changed to “Efficiency” and it’s now flipped.

Okay, good to know. Hopefully someone will document that at some point.
