Any of you BowTech tuning gurus able to answer a question for me? Based on this picture am I measuring the gap properly for checking the timing? http://users.adelphia.net/~jeramyk/P8290014.JPG

My 03' Patriot calls for a .215 gap and based on my rough measurement it looks like I'm off. Any suggestions on a better measuring device for a more accurate reading? Also, I can see the sharpie timing lines on the cam, how should that timing mark be lined up with the limbs?

Thanks for helping a timing newbie.
