Certainly does, but gravity is a constant value that can be calculated for...
Wind, on the other hand is never the same and simply cannot be quantified accurately over any appreciable distance, especially @ 800yds in the field on a deer. Sure Kestrel can get you accurate wind data at your muzzle, but what about the rest of the way? Guessing that is voodoo magic, my friend...
I'd be more apt to believe that my chrono were reading consistently slow and I misjudged the wind call than I would the other way around. The only way to test your dervied b.c. in the wind scientifically would be to artificially produce that wind velocity accurately for those entire 800yds at a given angle and see how far that bullet sails off course...
So consider your data above again. You make a wind call at the muzzle of 10mph, but it actually averages 7 mph over those 800yds, due to terrain & gust variables. That minute misjudgement would net you the same miss due to the wind call...
Calculating drop is easy.
Calling wind is voodoo magic...
