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??
