I’m not entirely sure I fully understand what you mean, but these are the results I’m getting at the moment. The first example showing an especially interesting case where only one axis seems to be off. (Superimposing orthographic screenshots from the top showed a pretty perfect match in the other two axes.) And the second example shows what I usually get. Scale and Orientation are spot on in both cases.
