Chairgun changing pressure and elevation settings

Well I did some homework and came to a conclusion. It doesn't matter what altitude it thinks you are at if the barometric pressure is correct. I hope someone benefits from this. Pressure is used in the calculations. Elevations will give you the average pressure, not measured pressure. Measured pressure lends toward accurate calculations. So if I have proper, measured pressure, I'll let the elevation say whatever it wants. Happy shooting.
