Got a point there Berty
Trajectory is exactly the same whatever the scope height is.
2 clicks less for 1" extra height at 55 yards only because zero is further out, my case 25 to 30 instead of 22 to 25 yards, that being the 2 clicks.
With the 80 March it would be so minimal as in inches, max error +/- 3/4 yard or its out of focus what ever the lighting. It would affect the 10-60 though if no detail there.
White used to come in 1 yard sooner with an old 1994 Tasco mark1, learn it.
