I think my point was lost in translation Rock. What I was trying to say is that at lower power people are generally shooting shorter range. In RR's calculation there, .000693" movement of the barrel would shift point of aim at 300 yards just over half an inch in a perfect scenario without wind drift and such. .6297 to be exact but at 700 yards is almost an inch and a half. That's a very tiny movement and predominately no real bearing on shorter range shooting therefor no real bearing on lower power on the scope. BUT when you are getting out there to 800+ it becomes a pretty big shift. Stadia shift from heartbeat at high magnifications can cause a pretty good bit more than .000693 in your lessor quality scopes but still not really affecting your shots at closer ranges where extreme magnifications aren't generally used unless you are trying to pick out a hair to shoot at 200 yards but even then you wont experience TOO much lateral movement at that short distance. Sorry I wasn't a bit more clear on what I was trying to point out. Us old folks try to save as much time as we can ya know
