Moving your sight in the direction of the arrow is the correct! But the drop of your arrow all depends on the speed of your bow. Even with a pendulum sight? I know the manufactures all tell you the if you sight it in at 20yrs on the ground that it will shoot dead on out of a tree out to 30yrds. It is not true for all bows. Also make sure you are bending at the wast when shooting even with a pendulum sight you still have got to do that! If you don`t! This can also make you shoot low. Good luck!!
