A new version of FSRS, FSRS-4.5, has been integrated into the newest version of Anki, 23.12. It is recommended to reoptimize your parameters. The benchmark has been updated, here’s the new data:

Note that the number of reviews used has decreased a little because LMSherlock added an outlier filter.

RMSE is the root mean square error, can be interpreted as “the average difference between predicted and measured R”

Junyao Ye, also known as Jarrett Ye is the author of the new stochastic model of spaced repetition
“It’s a substantial extension of my previous conference paper A Stochastic Shortest Path Algorithm for Optimizing Spaced Repetition Scheduling. FSRS is based on the model proposed in that paper.”
