I’ve legitimately buried bats and had a seance to rid my team of a hitting slump lol
Imo the key is to not launch the arms before the body. Don't slot the elbow but keep the scap "pinched" until the body launches so that the elbow is pulled down by the back shoulder and not lowering independently. After this happened the scap can release and the elbow adduct and the hand supinate.
