The point of aim (or dot on the target) usually is bigger the closer you get, so pin float gets to be a thing. Like 5miles said, pick smaller aim points instead of bigger "blob" which when you are in the area of the blob and release your arrow, you may be way left in the blob or way right. Aiming at the line like he said gives you a smaller target and more precise aiming point.
