Do you not use an anemometer or even a direction meter such as sailors would use and wait for the exact wind speed and direction you've calculated for before making the shot or is this a waste of time over distance as the wind in two places, 1km apart will not be exactly the same in any case?
The other thing about wind is that it brings in a slightly 'random' element that slightly reduces the level of skill involved. It must be fucking annoying beyond words to let off a round and then feel an unexpected gust ruffle your hair!
Having said all that, I'm still more impressed by William Tell. He had no gadgets ;-)
