The beauty of diopters is that the eye automatically centers the two apertures with each other. Sight alignment is done subconsciously. Doesn’t work as well when the front post can move vertically in the front aperture because the eyes align the apertures, but then the post must be centered, so the apertures are taken out of alignment to do this. That makes the initial alignment pointless and you now have to fight the subconscious desire to keep the apertures aligned to keep the post centered in the sight picture.
I reached the same conclusion a long time ago, and gave up on the "HK" style front sights. But with this sight, the surrounding aperture is movable and indexed on the bottom of the post. Push the surround down, adjust the post (finger adjustable), then raise the surround back up. Thus the surround is always in the same position with respect to the post, that is, with the post centered.
You're not centering the post within the surround, you're centering the surround around the post...
