Inconsistent number of reviews when clicking `optimize`

Another confusing toast:

Why are they different? I think the first one should be Only 0 review was found.

3

Can you provide an example apkg which demonstrates the inconsistency?

The ‘insufficient history to perform this operation’ is triggered in other cases such as when there are no learning steps in the review history (get_optimal_retention_parameters())

4

It could reproduce the second issue. When I search preset:all prop:ivl>100, there is zero card queried.

5

For the first issue, I guess the computeWeightsProgressString isn’t emptied.

6

fsrs-rs’s smooth_and_fill may return FSRSError::NotEnoughData, which turns into the 500 error.

I will update the progress code to clear out the old text at the start of an operation.

But the number of reviews is zero, which is less than 1000 reviews. The less than 1000 warning should pop up before smooth_and_fill.

I’ve pushed a change that will do the count check at the start.
