I'm looking this too, it would be Konami's dodge style, we've seen enemies can dodge pretty good in Konami games.
I was thinking if i put choose() expression to get pasive by 50% chances via the distance condition, then create 2 variables as sucess and fail, if is succeded, the sprite dodges using bullet with high speed at short time to left or right via bullet or sprite angle where it aproximates, last by 0.5 second, if is failed, it couldn't dodge.
If you don't understand, i will make a .capx when i get chance
