captn Mauser,

the farther you put your pins away from the bow, the more the pin gap will grow which will give you the most accuracy. Thank about the ultimate sight, it would stretch from you to the target and you could put your pin right on the target itself. Now, the difference would be if you used your 20 yard pin for a 30 yard target, how much would your arrow drop? That would be your pin gap.
