The optimizing presets message is technically incorrect. The parameters have been already optimized. It's just about the memory states of the cards being updated using the new parameters.

The optimizing presets message is appropriate for the optimize all presets button, though.

Here is the Anki code for reference:

@user1823 that's what I get for trying this without a reference image 😁

Then again, it led to a bugfix, and it's one of those "5 minute" changes to fix

Thanks for the guidance!

I like this less (% progress is much easier to grok), but it's ecosystem compatible
