Sadly wind dont blow constant a lot of the time or the same direction. So the pellet dont move X amount with a constant mathematical formula as the windage lines have been calculated at. Their only a guide and
another aiming point. When you pull the trigger its the shooters decision as to what line they actualy use based on how far the pellet will move. Lines dont make that decision. Use the wrong line and you miss.
