RE: adjust for windage on sights
I know this is an old post, but I'll chime in anyway just to clear things up.
"Adjusting your sight for windage" in archery doesn't have anythign to do with the wind.
It just refers to the left-right position of the sight. The 2 ways to adjust a sight are Windage and Elevation, regardless of whether the sight stays fixed in place, or it is adjusted in the field (like for long distance rifle shooting).
Set your bow's sights to hit dead-on at a certain yardage, and leave them there.
If there is a strong wind, you shouldn't be shooting unless a very short distance.
I don't know anyone who would consider touching their sight adjustments on a bow in the field.
