How does AB calculate zero changes in Barometric pressure?

[Chukwithak]

I'm used to 4DOF which takes in the environment when you zero. This makes sense to me because if I the BM decreases the air is thinner and ballistics will change.

AB I have seen say that your zero at 100 yards will not be affected at 100 yard zero's. Ok I understand that. 100 yards is minute. But if I take that zero and extend it to 1000 yards at a different pressure, thats going change things right?

Now I understand that AB should be able to take into all of the data at a current location to predict the changes (bullet,speed,AP,etc) but it does not know my zero.

Am I over thinking this?

Also, does the paid app assist with Kestrel w/AB or Vortex Fury or is it mostly a standalone app?

I challenged you to mess with it at different density, altitudes temperature ranges, pressure changes and all that stuff and see if you zero even changes it will not. A 100 yard zero is used for the main reason that everything is a dial up if you use anything else, then your zero environmentals matter and it’s not as easy to predict.
