Eremicus,
I use your system for focusing.
The problem with "properly focused" is most folks can't do it as well as you can; maybe I'm one of 'em. Therefore they have to go with what looks good to them the way they use their scopes.
ALL of my rifle have scopes with A.O. or S.F. NEVER have I had a problem in the field by setting the distance to about 150 and leaving it. When there is lots of time I can play with my scope's adjustments; both objective and magnification. Otherwise put the sight on the game and fire.
