"Radial" and "Longitudinal" reference (TGM) the Pressure Point (Senses and Directs) Alignment with the Clubface at Release (Pulley). "Radial" is termed to describe the PP at Right Angles to the Clubface and "Longitudinal" is termed to describe the PP which is Parallel to the Clubface.

The Pivot, Power Package and Pulley all contribute to Angular Acceleration regardless of Hitting or Swinging. The term "Throwout" is used to describe the Clubhead being moved around the Pulley by Centrifugal Force (Radial Acceleration) while "Driveout" is used to describe muscular effort propelling the Clubhead around the Pulley (same Radial Acceleration). Regardless of Method, it is the "Pulley" that creates Clubhead Acceleration and not the type of Thrust or how the PP is Aligned to the Clubface.
