in TSPP and TZ I stack for the likelihood of completion of a mode or multiple modes in the given time, additionally when multiball and stacked modes are running your per whack-a-mole hit on each ball is higher then a single ball. aka big points. also if you get a mode completed or bonused or jackpotted etc.. then its BIG POINTS. I like caps so i strive for those BIG POINTS. after all its not a game of who can play with their balls the longest. but who can WIN! (and winning unlike the game of soccer where you can tie, is important dont ya know) so if your not a winner you wouldnt want to stack...

are you a winner?
