I may have figured some of this out just playing with the meter and StrelokPro and the 4DOF apps. With StrelokPro, I think I have to calibrate the meter to the app with the meter and my phone facing in the direction the wind is blowing (the wind at my back blowing into the meter). Once that is done if I point my phone in the direction of the target while keeping the meter facing the wind, I get a windage reading that makes sense. If I calibrate with the meter and my phone facing into the wind I get the complete opposite (left instead of right)windage reading that I should.
With the 4DOF app it's just the opposite. I need to pair the meter when the meter and the phone facing into the wind.
Either way, it seems that when I initially calibrate the meter with the app for the wind direction, the app automatically stores that information until it is calibrated for a different wind direction.
Of course this was all figured out in my driveway and still needs to be confirmed with some shooting results.
