The guys are right final tuning and sighting in has to be done by you. I would try a peep it will help you anchor consistently. Try to get a double anchor for example string touching the side of your nose and your thumb behind your jaw bone or fletching touching the corner of your mouth. With these you know you are lined up the same shot after shot.
