RE: Cam timing
Interesting, WWAG. How does this work? I'm really curious, but that looks very innovative. Does it attach at a specific reference point on the cam, and the point extending out to the string used as a measuring point? You can PM me if you don't want to discuss the details in public.
Anyways, to the OP, the dots are just starting points. It's advised to not base timing off the marks specifically. Rather, draw back the bow (preferably on a hook are on a draw board, but having a second person watch you draw back will work, too), and watch the draw stop modules. They should both contact the cables at the exact same time, and both should contact about 1/8" AFTER the draw stop hits the limb to allow that little o-ring to compress.
