The whole point of using a jig for sharpening is to standardize your process so it returns the same results every time you sharpen. The stickout can be anything (within reason) that gets the bevel angle where you want it. I believe that the stickout (combined with the distance of the pocket from the wheel) has the most effect on the nose angle. The leg on the varigrind, the pocket distance, and the stickout all combine to put the appropriate angle on the nose and wings.
