You can reduce these deviations to absolute zero by making sure the rifle is level and the scope is mounted level. You're example of the path of the bullet through the bore intersecting with point of aim through the scope does not happen. Intersection only happens vertically. Your insignificant measurement now becomes significant.

Yes you are using subtensions as windage. No one in there right mind would do that. You can argue until you are blue in the face. 0.7" at 1000 yards is negligible especially in a hunting situation.
