RE: How height affects accuracy
Elevation and angle have nothing to do with archers shooting high...it' s the lack of knowledge and these archers are dropping their bow arm and not bending at the waist.....if you bend at the waist, it doesn' t matter if you are 10 ft up or 40 ft up.....However, the higher you go, the more the difficulty level goes up....you must aim for the exit hole and think about the path of the arrow through the animal.
Through the years of hunting and competitive 3D, I' ve shot from ground level to up as high as 30 ft....and from ground level up into trees at bear targets or uphill on mountian lion targets and more....none of these elevations or uphill shooting is affected high or low as long as you bend at the waist....
If you truly believe you shoot high because of elevation...you better get out there and practice bending at the waist.
