Most of the " Pros" come down from the the top. The reason? It is easier to stop and hold the site where you want it on on the way down rather than " lift" the bow to the site picture. It is intricately tied to panic target in a subtle way. As has already been mentioned some will " freeze" in an attempt to get on target on the way up. You have to " push" the weight up and this only adds to the handicap. Letting the bow " float" down on the target is an easier route to take, you are not fighting with so many different variables in your muscles and head.
