Re: Anchor point?
Try drawing a bow with the shorter draw length. If you come up against the "wall" before you feel your at full draw, the draw length will be too short. I would say that the information given by the bowshop dude is somewhat ambiguous as your anchor point is dependent on your flexibility. The method that you described in obtaining the 28½ draw length is one of the most prescribed methods and in your case is probably correct.
Using a release will have a tendency to shorten you draw length. When selecting a release, bear this in mind.
