I am no expert on bow tuning but does the fact that I'm shooting somewhat off from the "designed" center shot that my arrows are not spined correctly? I'm shooting accs 3-49s which is what the chart shows. My bow is at 60# and 28" draw.
It seems you would have max efficiency if the theoretical center shot ( 1 7/8") and the actual when bare shaft tuning would be the same. Is this correct??

I am no expert either and mostly go by what I have read in the Easton tuning guide. I think if you had to move away from the theoretical center shot of 1 7/8" then either your spine is not quite right or because of the pressure point of your particular grip. I have seen the same bow/same arrow need tuned with a different rest center shot when going from one shooter to another due to grip/hand position.
Which direction were your bare shafts impacting to cause you to move the rest to the right? I can't imagine 3-49's are too weak for 60 lbs. I had to move mine to the right because my 3-28's were weak and impacting about 8" to the right at 20 yards. I got them now hitting about 2" to the right at 20 yards and don't want to move the rest anymore. Just for the hell of it today I shot some over spined 3-60's and sure enough the bare shafts hit about 8" to the left of the fletched arrows, confirming a stiff arrow.
