RE: Practicing at short distance - do any good?
Practice at any distance is a good thing if it is" good practice " by that I mean if you are concentrating on improvement ( good form, realese, anchor, and shot placement, ) and in addition it will keep your muscles in shape which you would be amazed how quickly they will go away. Unlike compounds to become really proficent with traditional equipment it needs to become a life style instead of a once in while hobby. In other words shooting year around no matter what the distance is required. As far as your need to draw and hold for a few seconds I think everyone would benefit from this practice there are some people who can draw and release as soon as they touch anchor and hit very very well but they are not the norm and I believe they to would benefit by settling into there anchor.
