Distance is mechanical,wind is Voodoo...if only as per always.
BC do many things and most are in a hurry to look at it all wrong,which I rather enjoy. Extrapolation is key and it's never not intellesting to compare/contrast fps of impact velocity lost,per (1) yard of distance and how many inches of drift are incurred,for every (1) mph of wind.
I personally weigh impact velocity and drift,a bunch more than a whole fucking bunch. for distant ZipCodes,the Transonic distance matters muchly too.
Wanna fuck with heads?!? Simply extrapolate a "lowly" 21" 7-08 and 180 ELD's at 2600fps. Then think recoil,grains of powder,barrel life,round count in magazine,etc...........
