I understand what you are saying. But, am I wrong in believing that if I am getting improper flight in an arrow, that paper tuning will let me know what is wrong assuming that it is not clearence, tiller, or the like and will give me a starting point in which to tune by. An eleven o-clock tear will need a different adjustment then a four o-clock tear won' t it. How can just looking at the arrow flight give you the same type of tell tale starting point that a paper tear will? To me, a paper tear is not as complicated as seeing a bad arrow flight by eye and not knowing where to start.
