interesting tool but i just close one eye and sight.
One way to improve the ease of sighting - use long quill stems. 180s are a breeze. Just hard to find.
For me, seats are easy. Nose wants to be over about midway between (traditional steel) TT edge and center. Being off a little matters zero to my soft parts and askew is askew. Different amounts don't offend differently.
