Thats the only glaring issue I've seen in what you are working on.... sounds like you are going about it just right. Shoot at the center and find the densest part of your pattern with your 10" circle template... hopefully its in the middle of your paper, covering your point of aim and configured about 60/40. (thats 60% of the pattern in the top half of the target, 40% below it.... 70/30 is ok too).
