Once you've done 1000+ reviews in Anki, you can use the Optimize button to analyze your review history,
and automatically generate parameters that are optimal for your memory and the content you're studying.
If you have decks that vary wildly in difficulty, it is recommended to assign them separate presets, as
the parameters for easy decks and hard decks will be different. There is no need to optimize your parameters
frequently - once every few months is sufficient.

There is no need to optimize your parameters frequently - once every few months is sufficient.
By default, parameters will be calculated from the review history of all decks using the current preset. You can
optionally adjust the search before calculating the parameters, if you'd like to alter which cards are used for
optimizing the parameters.

This tool assumes that you’re starting with 0 learned cards, and will attempt to find the desired retention
value that will lead to the most material learnt, in the least amount of time. This number can be used as a
reference when deciding what to set your desired retention to. You may wish to choose a higher desired retention,
if you’re willing to trade more study time for a greater recall rate. Setting your desired retention lower than
the minimum is not recommended, as it will lead to more work without benefit.
This tool assumes that you’re starting with 0 learned cards, and will attempt to find the desired retention value

this feature requires a minimum of 400+ reviews. The calculated number can serve as a reference when deciding what to
set your desired retention to. You may wish to choose a higher desired retention, if you’re willing to trade more study
