I will add that you are looking at a computer output discrepancy of two decimal places. These programs will get you on target but the level of precision you are concerned about is unrealistic. The algorithms that drive these programs are by default, simplifications of reality. There are other factors not being considered. Like the swirling air pushing that bullet around differently to what the flags are showing. Or the difference in temperature of the ammunition and how that changes velocity between when you chronographed it and when you shoot. Little things like how long has that auto-loaded round been sitting in the hot chamber (oven) before you pull the trigger. Or what exactly your scope reticle has moved regardless of what the turret clicks say. Or how much the erector mechanism has moved from the last recoil as you chase the spotter around on the target.
Applied Ballistics sells custom drag models for their program they claim make the computed curve more precise. This is especially relevant at Mach 1.5 and below as G1 and G7 curves diverge.
I can't remember the last time a ballistics calculation put a bullet exactly where it said it should go to my definition of accuracy. But, they get you on steel/paper and that means a 'hit' on what you are shooting at.
