NV-500 owners – question about the built-in inclinometer and ballistics calculator

I'm not entirely new to scopes or basic ballistics, but this is my first experience with a digital scope. The inclinometer sensor is throwing me for a loop.

Normally, with a traditional scope, I would zero at flat (0 degrees), and then moving forward, I would manually enter my shooting angle into a calculator based on the specific shooting situations. My understanding is that zeroing at an angle (let's say -8 deg) cannot get you accurate ballistic calculations for anything other than shooting at -8deg AND at the same distance that was used during the zeroing process. (correct me if I'm wrong)

So, with this electronic scope, when you use the rangefinder and the scope's software solves the drop, is the live/current inclinometer value actually fed into the ballistic calculation, or is the software only using the manually entered shooting angle that is set in the ballistics menu?

I'm conjuring up scenarios where there would be conflicts and overlaps between the live inclinometer angle value and the manually entered angle in the ballistics menu. Obviously, this would result in miscalculated ballistics from the scope. I did pose this question to the manufacturer, but I'm not getting an entirely clear answer.

@MMP Good question. I’m interested in reading the answer. Who is the manufacturer of the NV 500? Is there a brand name on your unit?

It is a company called OneLeaf. I followed up with them for a few emails on this topic, but I get the sense that they don't fully know the answer, or maybe I'm just not understanding their responses. I've received some vague responses, and responses answering questions I didn't specifically ask. In one of the emails, I was told that such a small angle really wouldn't make a difference. I get it, it's not going to result in missing your shot on a deer at 75yd, but a small animal at that distance or further, it could make a real-world difference. Regardless, that reply made me lose confidence in the entire interaction.

Anyways, I've thought about this a bit more and have come to my own conclusion that the scope is not feeding the angle into the ballistics calculation. When I tilt the muzzle, the predicted aim point does not seem to correspond to the angle change at any given distance. Additionally, if the scope was feeding the live inclinometer data, I don't know why the ballistics menu would bother having a place to enter your shooting angle....but then I questioned why bother having inclinometer data if it wasn't being used for ballistics. I thought maybe the angle value in the menu could be the angle at which you zeroed the scope, but the manual says otherwise.

My guess is the inclinometer is supposed to be used by the shooter so they can more accurately determine their current shooting angle and enter that into the ballistics menu. It would make more sense for the software to use the live inclinometer to calculate drop rather than having to manually enter based on each shooting situation. In theory, allowing the software to using the live inclinometer would also allow you to zero your scope at any angle and have correct ballistics at any angle and any distance.
