How rare is it to catch a Mewtwo first-try with 4/5 health with an Ultra Ball in Ultra Sun? And the percentages for it?

Question

Because that is what I just did in Ultra Sun, so I got curious.

Answer 1

You have a 3.392% chance of capturing it per ball.

This is no status conditions, 80% health, Level 60 (as this is an Ultra Wormhole encounter, which is what I'm assuming).
