RE: drop away timing
You can see where the rest is dropping by spraying foot powder spray on the back half of the arrow. See if the powder was scratched off. Of course you have to have someone spray it at full draw and you have to have a target that stops the arrow quickly so that it doesn't wipe off the powder in the target. Ideally it should be falling somewhere around the label on the arrow. Adjust itso thatit wipes a mark in the powder on the arrow until the label area and leaves it untouched past that and you should be good. You can wipe it off between shots. That spray is great to have around for arrow rest and fletch clearance testing. Just spray your arrow/fletch and it will leave the powder on whatever it touches.
