This method of getting the two lenses closer is not perfect. In practise I find it does not cause a significant problem.

Interesting, for me even 0.5% height difference is way too much for comfortable vision. Apparently I am not a "hardcore stereoscopist"

Seeing a perfectly aligned image or an image with a small height difference is like night and day for me. The latter always causes some strain in my eyes.

Using StereoPhotoMaker the main object in the scene is aligned so its height for left and right is  exactly the same  ( say to a 0.1% or less matching ). Other objects in the far distance will not quite match in height ( as you pointed out ), but these objects are not the main focus of the overall image, and in practise  do not cause a problem. As I said putting the two cameras in a stagger arrangement to reduce the base distance is not perfect. When I have done this , I am usually doing a stereo movie clip rather than a still.
