I have a question about draw length. From what I understand the AMO draw length measurement is to the centre of the button + 1 3/4 inches and this measures exactly to the back of the bow. My arrows measure 29 1/8 inches to the end of the shaft and I've found that I'm drawing such that the shaft end is in line with the back of the clicker plate screw. Measuring from there to the back of the bow gives me 5/8 of an inch. Does that make my draw length 29 3/4 inches? The reason I'm wanting to know is because limb draw weight is measured at 28" so I would like to know how much extra weight I'd be pulling. If my measurement is correct then I'd be pulling around 3# above the marked weight, right?
