One problem is that you can not keep the sight centered properly if you don't bend at the waist.When you change your anchors,you will move the site alignment out of center.

Another problem is that you change the distance from your eye with the peepwhen you drop your arm,which changes pin gap and changes the size of the halo.It also changes draw length.


BUT,imo,if it is possible,(which imo,it is not) to keep everything centered,then the arrow will hit where it is aimed.The answer is it is a trick question because it isn't possble.
