The picture of the guy being dragged by the ball when he throws it hard amuses me more than I'd like to admit. Throwing it felt a little clunky to me too, and specifically it seems due to a mismatch between how full the bar is and how far the ball actually gets thrown -- about half strength seems to make it go just as far as full strength, so maybe just rescaling it so it matches the distance would make it feel better? (Unless it's not a bug and its a feature of making the distance traveled fall sharply if the inmate starts getting dragged.)
