FSRS New Card Interval Inconsistancy

I’m curious why when using FSRS the new card intervals are not consistent.

Assuming I answer all the cards right the first time, I would assume all intervals would be the same, but they are not. One card would get 3 days, another 7, another 8. Is it taking the time I take to answer into consideration?

No.

If you want to understand where those come from, it’s explained pretty well in this technical explanation of the algorithm. There’s no paragraph links, but scroll/search down until you find this section –

So initial stability has to be estimated in a completely different way.


The first four parameters that you see in the “FSRS parameters” window are the initial stability values.

With the default parameters, you would see a first interval around 2-4 days when you graded your answer Good, and around 6-8 days when you graded your answer Easy.

In addition to what is written, this allows you to make your daily workload more uniform.
You should go through the manual at least once.

Lol I like how our thinking is so similar. That’s what I thought but dae says no it doesn’t. This probably has to do with fuzz factor and maybe when a card comes up in the new queue? I really can not say but that seems plausible from my experience. I read what others said. Ignore this.

I went through the manual several times over the past 4 years
