Science!
Yeah, I don't know, I'll just leave all this scientific physics talk to those who want to argue over it and just get on my bike and ride. While you guys can think about how the springiness of your frames are affecting your power curve, I'll just ride along and think things like, "Oh look! Cute bunny!"
So I guess the OP is correct, stiffness of my frame doesn't matter because I never think about it. I just got sucked into this thread by the double entendre.
