Good question. I am also confused about where to measure the bolt from. Is it the near edge, outside edge, middle???
Luckily for me all of my bowtechs have had the marker lines and I haven't had to know where to time from. But I helped a buddy tune his 03 Extreme yesterday and he had no marks. So where do we measure from??


As far as the timimg marks go. Perfectly centered with equal amount of limb exposed before the mark on each side of the limb while looking at it from the side would be ideal. (put the limb in the middle of the marks).
