I don't agree at all with two of the recommendations.
First, thrusting the glove arm forward and then pulling it back like a piston serves no purpose in complementing the movement of the body forward or completing a hard delivery.
The glove arm should swing forward and up in an arc mirroring the ball arm. At 10:00, the glove arm stops while the ball arm continues around the top of the circle. When the ball arm gets to 2:00, both arms sweep down, like making snow angels (those of you down south, call a friend above the Mason-Dixon line). The glove arm then comes to rest at the thigh/hip, not passing behind it. The balance of both arms working in unison brings more power to the pitch.
Secondly, in no way should the glove arm be swept past the hip to behind the leg -- it must stop at the hip. Otherwise, this motion turns the body back to a closed position BEFORE the ball passes the ballside hip --- not what you want.
I think the arguments for making the glove arrive at a defensive position during the pitch delivery are superfluous. Maybe the pitcher should also bend at the waist instead of standing tall to better protect herself.
