if i'm shooting a 223 or the like and have a 90 degree wind of 10 miles an hour (long grass is moving gently) i hold 1"/per 100 yds. a 45 degree reduces the hold by half. thus i hold 2"/100 for a 20 mile an hour,(leaves blowing and small brush moving) and 3" for a 30 mph (trees blowing) thus with a 10 mph at 200 it would be 4" etc.
for a 45 deg. wind the values are halved and for a larger caliber like 243, 257 etc. they are halved.
while not exact my any means, it does work for me in the field
