Interval modifier not affecting large, mature deck

FSRS is a new algorithm for Anki. It is more accurate than SM-2. It can help you to achieve the target retention. I write a Usage for it:

How to use the next-generation spaced repetition algorithm FSRS on Anki?

Long time no see, guys! Recently, Anki has updated to 2.1.55 with the support of custom scheduling with memory states. Today I want to introduce how to use the FSRS4Anki custom scheduling. Introduction of FSRS4Anki FSRS4Anki, aka Free Spaced Repetition Schedule for Anki, is based on the three-component model of memory proposed by Piotr Wozniak and the stochastic shortest path algorithm introduced in my paper. It makes great progress in memory prediction and scheduling optimization. Prerequis…

And FSRS4Anki helper could reschedule all your cards based on your cards’ review history. It doesn’t need a very long time to take effect.
