What bullet are you using?One shot at each distance. Then I set the scope turret to 9.75 MOA and shot 3 rounds prone off the bipod. 3 Shot average impact was 12" high
I still don't understand why the drops do not correlate with the ballistic trajectory. Since the scope wasn't dialed between shots, it was not part of the equation. The only thing I can guess is that my bullet was shooting flatter out to 500y and the 600y drop was an anomaly. If I had shot groups I might have gotten more confidence in the data.
I went the 100y range today. Temp 83F. I started with a POI test with the last zero I used in the colder temp and higher elevation. The impacts were high by the same amount that I altered my zero for the elevation and temp change.
I did a tracking test on the VX - 6 scope. At 10 MOA the POI was 10.75", 20 MOA = 22', 25 MOA = 27.375". I also tracked R 5 MOA= 5.375", L 5 MOA= 5.5". Returned scope to zero and POI was good.
I also checked MV of frozen cartridges vs warm. The MV cold 3047, 83F warm 3089. The POI shift between warm and cold was 0.5 Up and 0.8 L.
My take on all this is that nothing is wrong with the scope, rifle, or mounts. The environmental changes caused the POI shift. I will need to re-zero again when I get to Montana.

It looks like your scope is over travelling. Make sure you adjust the turret values in your ballistics program. Ballistics aps are not greated equal when adjusting these values.
There's a lot to it when you really get into.
Your charts are always a prediction (key word) to drop. Mathematics do not take into consideration: human error, and changing conditions.
Human error can be broken down to info put in into ballistic software, technique in shooting or affecting the harmonics of the gun.
Changing condition can be node changes on a cold barrel, environmental or bore conditions, ammo etc.
Next is even if your chrono is a magnetospeed or labradar and your bc is taken off the box, doesn't mean that any of it is without errors. Hence why everything needs to be verified and trued to meet real world results.
The bullet doesn't lie. It's better to true out to 700-800 yards and work your way back in. Then again we'll beyond 1000 in my opinion.
Lastly, taking accurate environmental readings is also important to assist in quantifying your charts.
I am sure Aaron does not know how to shoot...

Here is a Vx6HD out of the box with a solid zero....
It was dialed 32 moa and travelled 35.38 inches. 32 moa is 33.504 inches.
