Nathan Stephens' Swing Lab @ Hartsbourne Country Club
CLUB AND SWING DATA
Club head speed measured on the sweet spot at impact with the ball. Club speed has a direct influence on the ball speed if struck on the club face center.
Club Speed Profile
The speed of the club head’s sweet spot away from the radar, measured pre and post impact with the ball. From the speed profile, a player can determine swing speed consistency, energy transfer efficiency, and proper club extension post impact.
Club Acceleration Profile
Acceleration of the club head’s sweet spot away from the radar, measured pre and post impact with the ball. The acceleration profile will indicate the rate of closure of the club head due to shaft bend and club release by the golfer.
Club face angle relative to the radar’s target line, calculated at impact. Face angle will influence the direction in which the ball starts relative to the radar’s target line.
Face To Path
Club face angle relative to the club path, measured at the moment of impact with the ball. Face to the path will tilt the spin axis if impact occurs on the club face center.
The loft of the club at impact. Dynamic loft influences the launch of the ball and is a result of the static loft of the club, shaft bend at impact, the angle of attack into the ball, and the amount of forward press a player has at impact.
Angle Of Attack
The angle at which the club head’s sweet spot approaches the ball, measured at impact with the ball. The angle of attack will have an influence on the ball’s launch angle, and spin loft.
The direction of the club head’s sweet spot relative to the radar’s target line, measured at impact with the ball. The path is influenced by a player’s angle of attack, horizontal swing
plane, and vertical swing plane.
The contribution to ball spin as a result of the effective loft on the club face presented to the ball during impact, which is approximately defined by the difference between the 3D angle of attack and 3D dynamic loft of the club at impact.
Horizontal Swing Plane
The direction of the club’s sweet spot relative to the radar’s target line, measured at the lowest point in the swing.
Vertical Swing Plane
Vertical angle described by the trajectory of the clubhead relative to the ground.
