Dear Syntax,
I really can't see even one reason for your post.
Your first photo is a paradigm that can not happens. Never!
Your third photo also shows a misalignment. Maybe a slight but true. Any difficulty that arises always, it has to do with the cantilever alignment and not with the stylus. Moreover, the centering of the protractor's needle to the pivot point, is by far the most difficult part. At least, this is what I want to believe. It is so obviously basic & easy to put the stylus into the hole, that about your third photo, I prefer to believe that you take a shot from some strange corner that can cheat the eye. The point of discussion is the prefered alignment, together with the accuracy of the protractor. The skill of the user to follow the offered precision is irrelevant. I'll take your examples as were about the difficulty for a successfully precise alignment that offered to the user by the Dennesen, in contrast with the more easy UNI-Protractor.
