RE: shot placement on target from treestand..
You don't have problems with this if the bow is sighted in from a tree stand, thats what I do every year before the season, that way I don't have to adjust for elevation in the stand, except if the deer is 15yds or less. Probably the best thing to do if you have an available stand and tree, set it up at your desired stand height and shoot away, you will notice a big difference from shooting from the ground.
