Altitude vs. Barometric pressure

Yep that is why I rely on JBM's program and can inout different things, but I make a winter chart for drift/drop and a summer one and for my hunting needs it works quite well, thanks for the program JBM!

Whether you are at 2,000 feet or 7,000 feet, if the ABSOLUTE pressure is 26" inches, the flight/drop will be the same.

Grab your Kestral and get on with the business at hand.

.

So just to clarify for the umptenth time, my kestral is giving me ABSOLUTE pressure? If that is the case then it seems we are making this much too complicated. Or is it absolute only after I have recalibrated it? what If I am buried in the woods for a week and have no way of recalibrating before a shot?

forgive me, Im still confused
