Overthinking & overintellectualizing this subject! It's simple physics & a simple scope level minimizes or even corrects the problem. TYPE of shooting has no bearing on the real physics & gravity. It's all the same. Done!
Not sure if this is a math or a philosophy class. In the latter case, we will need to call on Karl Popper, who despite his name was not a shooter. He was much more than that.
Coming back to the point, I have EMPIRICALLY experienced, repeatedly with different guns, that highly mounted scopes magnify cant error. Likewise, I have been able to experience that a 2usd bubble level (mounted onto same instruments) helps avoid that distressing phenomenon. Leaving me deeply satisfied (and well fed).

After mechanically centering my scopes crosshairs using a mirror. I typically adjust my scopes using a level(s) while looking at a plumb line roughly 25 yards out hanging from a tree using a five pound weight on a non-windy day to align the vertical crosshair with the plumb line while the gun is level. Then a final check after tightening the scope screws down. Seems to work very well for me. There are wedges and such other methods to align the scope with the gun as well.
