Many more reviews than expected with new card settings

How reliable is this rule of thumb?

Not so much:

@dae

I seem to recall coming across users in the past with a review ratio close to 20x new cards.

@aoanla

FSRS seems very wrong about what it thinks I should be spending as time though - the simulator says I should be spending about 33min/day approximately

As you already said, your retention is very low and you’re doing a lot of intraday reviews, so it’s expected that you’re taking much longer than FSRS estimates. In the latest beta versions, Anki will also take into account the (re)learning steps so perhaps that’ll get somewhat more accurate.

@aoanla

My true retention for the past “month” (11 days of course at this point, but it’s the longest sample I have) is only 64% - my desired retention in FSRS is 90%.

One thing is, the higher the DR you set the more reviews you get. As your true retention was quite low, you’ll probably get more reviews now with FSRS. I suggest you try lowering the number (and see how much decrease in daily load you get using the simulator).
