I used to carry my wind gauge as a way to learn what wind caused different motion of the vegetation preferably lower vegetation like bushes. That way I could start to understand what wind caused the motion I would see at range.
I worked a project where we had 100's of wind profiles from 0 to 1000 yards and I don't think I ever saw one that was what I would call uniform enough that a measurement of the wind at my muzzle did much good.
