I am have relative litle experiance in scopes. But I have personally learned to use allot of time on adjusting the focus on a my scopes. When I got new glasses, I went over all of them again. I see in some threads when people are comparing scopes they have looked true all, but have they really adjusted the focus properly when they compared them? As I understand reticle can be unsharp, and parallax adjustement wheel can be off, if not the focus is set properly from the start.
