Wind DOES affect accuracy as shown by these tests.
I simply logged the Hit chance for each Russian unit in still air,
then went back into the editor and changed the wind to 'Strong' from the north, (ie- blowing from right to left in the pic) and ran it again.
The drift is
very slight with typical tank guns, but is predictably more pronounced with the lower-velocity 76mm IG.
(Incidentally I had to put the AT-Rifle further forward because his max range is 800m)
Conclusions -There's nothing we can do about drift anyway, its a fact of life so let's not worry about it.. :)
For statistics freaks here are the test figures -

"How many roads must a man walk down
Before you call him a man?
Yes, 'n' how many seas must a white dove sail
Before she sleeps in the sand?
Yes, 'n' how many times must the cannon balls fly
Before they're forever banned?
The answer, my friend, is blowin' in the wind,
The answer is blowin' in the wind"..
