What does % usable even mean?

[epistasis]

That's a great question to a very vague subjective estimate! To me it means that about 60% of the interactions are as usable as the prior version. About 40% of actions I undertake on my phone cause a visceral "ugh this sucks now" reaction.

Try toggling “Reduce motion” and “Reduce transparency” on and see if your percentage improves.
