The delay of wristcock release is better because of the fact that the maximum clubhead speed due to the #2 angle is attained almost instantly after the left wrist starts to uncock. After that, the speed from PA #2 decreases, that is, in every Swing, the clubhead is slowing down at impact. Therefore, the closer to impact you release #2, the less time there is for the clubhead to slow down. The late release and the the sweep release have the same max clubhead speed shortly after their respective release points(assuming equal handspeed and wristcock), but, because the clubhead doesn't have as much time to slow down, the late release gives more speed at impact.
