sharris10- Good question! A lot of people have trouble with this. I found that there are two problems. One was already states that the perception to the target has changed and mind is confused. If you stand at 10 yards and shoot in the kill and day long, pull up a chair and sit your find is confused by this different plane, just as shooting up and down hill, but once you understand that not a big deal, because the biggest reason is #2. We have a tendancy when we sit or shoot at angles, to not come to the draw as we do standing. We either short draw (sitting or shooting uphill) or long draw (shooting downward). we have to remember, that the draw is the same from the waist up!!!! No matter sitting,standing, bent over, up or down hill. If you bend at the waist the actual draw stays the same. Try it, go to your target stand up, come to draw shoot and arrow, then draw another, come to full draw and bend at the waist foward while at draw and bam you will still be in there. Just don't preload your shot!!
