Blanket statements like these make me a little wary... you can have runners that are too short and large, as well as a plenum volume much to great.......
throttle response anyone?

You right about the general statement though. But of the manifolds presented to be tested, I hold to my statement. I have 2 excel spreadsheets that I developed that calculate all the RPMs corresponding to runner length and diameter using a Hemholtz resonance model and inertial effects. I have quite enough experience with manifold design.
