Default Blade Static & Dynamic Balance

I have read with interest the post on natescape (http://www.natew.com/rcheli/ under "Setup, Balancing") regarding balde balancing. He asserts that if two blade are statically balanced on a seesaw type of balancer, there is no need to CG match them. In essence, he claims that the physics are such that the centrifugal forces act on the blades in the same manner as gravity. Thus, the lever effect that a CG mismatch has on the seesaw is the same as the increasing amplification of the force asserted by mass as it gets closer outside edge of the spinning rotor disk.

My question is: has anyone tested this theory in practice to see if it is true? In other words, has anyone flown blades that level out on a seesaw balancer (such as the Koll Rotor Pro), but clearly have different spanwise CGs?

I must say that I would love it if all I had to do was one step instead of three when balancing blades. I'm tempted to try the experiment myself, but I would love to have the benefit of prior experience first.

Thanks.
