Can we update it according to new data from simulations? This was calculated using default parameters and .90 desired retention.
The default limits can also potentially change.
The ideal defualt review limit should be either 176 or 196. But I’m not sure which one. This depends on whether reviews here already include new cards or not. @L.M.Sherlock It’s your code, can you tell us?
It’s better than a fixed rule for sure, but the ratios depend on FSRS parameters. You should treat this information more like a cookbook than a law.
EDIT: theoretically, it’s possible to run a simulation every time the user changes parameters and/or desired retention to determine the ratio, but it would be too slow to be practical.
I seem to recall coming across users in the past with a review ratio close to 20x new cards. I’m not sure you can come up with a number that works for everyone, and the existing message was more about setting a bare minimum, not exactly matching the new card count.
I think a limit that is not a round number is going to trigger some users’ OCD.
