You wrote that you click DOWN for a 90 degree Wind and UP for a 270 degree Wind. Are you sure? To me 90 degrees = 3 o'clock and 270 degrees = 9 o'clock, and I would click just the other way around. Any comments??
A wind from the left pushes the bullet right and down (my 270) and a wind from the right pushes the bullet left and up (my 90). Obviously corrections will be in the opposite direction.
