again not to argue, but in his book, the archers bible, pg 40-42,fred bear himself refers to snap shooting as short drawing or freezing on target and calls it an affliction making it impossible to reach full draw. the only cure being a " clicker"
he also then references true instinctive shooters as also being snap shooters who always come to full draw with little to no pause at the anchor.
hence the confusion, just saying
as i read that snap shooting can be either a form of target panic or if done properly can be a proper form of shooting.
so to the OP,if you are having trouble reaching full draw , try a clicker or some other form of " mental trigger " ie feather to nose , to signal your brain to loose the arrow
