Page script evaluation went up drastically

I checked my site performance on Lighthouse about 8 hours ago and since then, it’s drastically decreased. I only made cosmetic changes to a few subpages (not home page) in Softr and no changes in Airtable. Only integration is Fathom Analytics and I don’t think it’s the culprit.

Any thoughts on what might be going on here?

Performance on home page then → now:
Script Evaluation 1,039 → 2,366 ms
Other 403 → 965 ms
Style & Layout 167 → 294 ms
Parse HTML & CSS 36 → 94 ms
Rendering 27 → 34 ms
Garbage Collection 22 → 44 ms
Script Parsing & Compilation 18 → 52 ms

And now it’s drastically improved again with no real changes made. Case closed I guess, but still peculiar.
