The question i am wondering is does the tip of the arrow hit in the same spot as the fletched shafts. Just because the nock end is sticking in the target at an angle ie (/)(\) and the point is in the same spot doesnt mean your arrow is too weak. If your bare shaft pointsare hitting 5 inches to the right or leftof your fletched shafts then you have a spine issue. I asked a similar question about a week ago. One thing i didn't realize, whether it makes a difference or not, is that according to easton guide bareshaft tuning is more geared at finger shooters than release shooters. It is a good indicator for nock travel but i am not sure if it is as consistent at telling you if your spine is adequate. Like the others said shoot a bareshaft through paper to make sure you have good arrow flight then go to walkback and group tuning. For quick setups I almost prefer the short distance tuning procedure.
