Can someone help me understand what is going on here ?? quick target expert ??

Quick target has a line at the bottom of the traj readout : Elevation above angle of site: .0772 degrees etc and varies for zero, bullet etc.

I assumed it was the angle between the line of site and the angle of the bore, but not sure now.

I am trying to work out a multiple bullet/load setting for a single scope setting, IE have a lighter bullet zero'd at 200 yards, heavy bullet at 100 etc.

I put in the numbers of what should have worked, but in the feild it is way off.
