Hi Mike, if you're using surface-to-surface flow mode then the problem is that surface to surface mode maps between the UV coordinate spaces of surfaces. There will be some slight compression and expansion of the deformed objects in this mode, depending on how the surfaces are parameterized.
The parameterization of a NURBS surface cylinder is not totally evenly distributed across the arc length of the cylinder so it will not be a suitable tool for doing a high accuracy flow like you want.
However, curve-to-curve flow is done by mapping length traveled along the curve, so it is able to do this kind of work.
So instead of using a plane and cylinder surface, try using line and circle curve objects to do the flow and that may work properly.
