For one you probably experienced some string & cable stretching since last year, causing the need for the draw to be shortened again. Although over a inch does sound like little too much. Possibly the initial setup wasn' t exact also. But I wouldn' t worry about it as long as you get it right this time. Touching your nose with the string is an excellent anchor spot, and most commonly used. Its very consistant. Once you have it right, make a few pencil marks on your cam. I like to draw a line on each side of the limb for identification purposes for string stretch down the road. As far as the shorter draw your better off getting the right anchor consistancy. I find most have too long of a draw. I guess being men we get this macho attitude sometimes that longer draws, and more pounds means more speed. But that always leads to inconsistancy!
