In the beginning, you bow skill is just too low for great results but will get better as you progress in game and does make all the difference later on. When starting out, you'll need to be a little closer to your targets to account for the range of potential drift but that drift. It starts getting noticeably better after skill 20 and by skill 40 to 50 I hardly ever see drift and can even do partial pulls to shoot the same distance as earlier full pulls.
