Do VNS equatorial platforms have this design limitation?

[peterfrostad]

I've been reading up on various equatorial platform designs with the intention of perhaps building one.

Since I'm new to astronomy and the various issues related to mounts, perhaps this has already been covered at length by others. But because I haven't run across it, I thought I'd bring it up.

Doesn't the VNS method of building equatorial platforms have a design limitation with regard to precise tracking?

I say this because the north section is elliptical instead of circular. This would mean that a constant speed motor driving the elliptical surface would not create constant angular velocity of the platform.

The CS method, however, does not have this problem because the motor drives a circular surface.

Am I right?
