[Flash 8] easeOutBounce too bouncy!

Hey all, need some help here before my brain fries. I’m using Robert Penner’s lmc_tween.as easing equations to drop down items. Problem is these items are supposed to be heavy metal plates, and they’re bouncing just like regular balls. I’ve tried playing with the numbers in the .as files but can’t seem to affect the actual bounce decay heights, it just makes the whole thing all wonky. Any advice on this would be GREATLY apprectiated, thanks so much!
