Hi Colin, that's a kind of "Michelin man" type effect there! :)

Yup, that's correct - what happens there is as the sweep profile travels along a curve, it does a slow rotation about the curve's tangent direction. That rotation is visible in the "seam edge" of the resulting sweep surface.

But that additional rotation is a much longer distributed one, it's like an additional long coil, there isn't any way to cause this particular thing to rotate at a higher frequency to make more coils on it, because the purpose of it is to kind of minimize jarring sudden twists during the sweep.
