First make sure your 2nd and 3rd axis on sight is correct. Then make sure your nock height is perfect.I do this with bare shaft tuning at closer ranges (5 through 20 yards).Then shoot at a horizontal piece of tape at 40 or 60 yards with fletched arrows. Try and get all arrows as close to horizontal tape as possible. Don't worry about left or right at that time.If all of that has been done and you get the same results as posted above, then move your arrow rest to the left (away fromriser)in very small increments. Keep doing the test until you get all arrows in a vertical line.
