How is Manual focus pulling on Sony lenses?

Question for those who shoots motion with Sony cameras.
How precise is focus pulling, using a focus pull rig, on alpha and nex lenses.

For example with Canon L lenses is notoriously pretty tough. Once you set your focus point, it will be difficult to repeat it precisely using the focus mark on the focus puller wheel. The Nikon are better, and the manual focus Zeiss are quite good at doing it.

does anybody has some experience to share?
Thanks!
