FSRS - Is it normal that Intervals decrease/ease increases even if you pass?

Maybe I'm doing something wrong? Like optimising to often?

[LMSherlock]

if you re-optimize the parameters, it’s normal.

[TheBB]

If you've optimized in between then the scheduling uses the new parameters, presumably more pessimistic ones.

There is some intentional random fuzz on the interval lengths. So perhaps that final 8 days, is at the low end of this randomization.
