Not trying to be a smart butt or argumentative, but, out of ignorance, I have a question about the value or need to bare shaft tune. If, with fletching in place,the arrow flies perfectly due to the stabilization of the feathers what is the gain of the perfection of bare shafting? Perhaps the "work" the feathers do to stabilize the arrow draws off energy, but I have not heard this stated before. Is that a factor?
As for paper tuning, what distance is generally recommended for doing it? It would seem that distance would be a significant consideration due to the archer's paradox effect. I'm glad bear mike brought this up, as I have wondered about this also.
