Final ACT screw up

I hear that UCs look at all your ACT score and choose your highest composite score.
I my previous 2 scores were 31, 32 and I took the ACT again last Saturday and I’m confident that I got less than a 30, possibly 28.
WIll my admissions chances to the UC schools be lower because I took this last test? Was I in a better spot if I hadn’t taken this last ACT?

UC’s take the highest score from a single sitting so they will take the 32. Everyone can have a bad day.

Thank you.
