With no ball in front of me I can delay my random sweep longer, something I need to do.

Anybody have some insight on this thing?

Assuming you have your mind in your hands, rather than aiming your hands at impact location, pitch your right elbow to your desired release position. For a random sweep, that position will be before the elbow catches the left hip, but I can't imagine why anyone would want to do that. Most release when the elbow catches the hip. An elite few pass the left hip and seek the naval. Managing the elbow helps by taking the focus off the ball, which helps eliminate the hit syndrome.
