Well, in this old hillbillys' opinion if the string had stretched the groups would have to go up. It is my opinion that the cable stretched causing the groups to go down. If a string stretches it increases draw length and draw weight, if a cable stretches it causes the draw length to shorten and draw weight to go down. Hope this helps. Be safe.
