OK, I think I'll keep my rolling average for now, but weight the non-bullet waves less like GrubbmGait said.
@Xor, I'll also install RoboRunner, I remember I planned to install it earlier but I keep forgetting :-P On my desktop at home, I have a Ryzen 3 1200 4 Core. 175000 rounds sounds like a lot! I'll probably not test against the entire rumble, but 30 seasons of 35 rounds sounds good!
@GrubbmGait, I try to only change one thing at a time, so that I can tell what change did what. And I always like watching the last 5 rounds of a battle at the end =)
Thanks for the help, both of you!
