Arthur - some good points..... I am a tuning freak and i need to learn more about FOC. I too get paper panic and try a lil too hard when I am shootin paper during tuning... I also get a lil tense bare shaft testing...... I like blending it all... then see how I group at 40, I try and forget WHERE I am hitting (while tunoing) and concentrate on simply shooting to see how my bow is reacting to my setup......
