I ve seen it done by two different bow shops two different ways. One was right up next to the paper, and one was from about fifteen yards. They also both had different explanations or how they did it. The one up close said that the arrow shows truer movement from closer up with no chance of anything effecting the flight. The one from fifteen yards said that up close the bow puts so much force on the arrow that it flexes strait out of the bow. I do most of my own bow work and was wondering what yall thought about the different ways to tune it. Hope that wasn't confusing.
