Actually zone dependant... from where I"m at, like you, I"m 200 feet ASL basically... take that to 12,000 or so... my zero is off enough to miss to my tastes... living at say 8K, going to 12K, out to 500 I"d doubt that altitude makes much difference at all. Elevation angle of shot could always make a difference.

Edit to add, I'm not so sure its the elevation difference that messes my zero's up, I just know to check them, that they are usually hitting about 3-4 inches higher at 100 than at home.... but humidity, temps can factor in of course as well as pressure.
