I agree with what you are saying.
But as a point of information that
may be unique to me, I find that when shooting a handgun with both eyes open my point of focus is the target - I want ot know if it moves, and if so in what direction. This causes the handgun sights to appear like a holograph, they "float" in front of my eyes. This is perhaps why I prefer a sight with no bars, dots, squares, or dashes. Just black and bold, with the front sight filling as much of the rear sight as possible.
"Sight alignment" goes like this;
Threat recognized
Scan field of view for threats "helpers" while drawing
Bring focus back to primary threat as my handgun approaches arm extension
front sight: top even with top of rear sight, amount of light visible on both sides of front sight equal
break the shot
repeat
Of course, this would be a
horrible technique for a bullseye shooter, but I'm not one of those.
