Attack Angle: The up or down movement of the club head’s geometric center at the time of maximum compression.

Ball Speed: The speed of the golf ball’s center of gravity immediately after separation from the club face.

Carry: The straight-line distance between where the golf ball was launched from and where it crosses a point that has the same elevation.

Club Path: The in-to-out or out-to-in movement of the club head’s geometric center at the time of maximum compression.

Club Speed: The linear speed of the club head’s geometric center just prior to first contact with the golf ball.

Curve: The horizontal side movement perpendicular from the launch direction to the carry side.

Dynamic Lie: The angle of the lower portion of the shaft relative to the waterline at impact.

Dynamic Loft: The vertical angle of the club face at the center-point of contact between the club and ball at the time of maximum compression.

Face Angle: The direction the club face is pointing at the center-point of contact between the club and ball at the time of maximum compression.

Face to Path: The angle difference between the reported face angle and club path.

Height: The maximum height or apex of the trajectory measured relative to the elevation at which the golf ball was launched.

Impact Height: The vertical impact location distance relative to the center of the face.

Impact Offset: The horizontal impact location distance relative to the center of the face.

Landing Angle: The angle the golf ball lands at relative to the horizon and at a point that has the same elevation as where it was launched.

Launch Angle: The vertical angle the golf ball takes off relative to the horizon and measured immediately after separation from the club face.

Launch Direction: The horizontal angle the golf ball takes off relative to the target line and measured immediately after separation from the club face.

Low Point: Distance from the club head’s geometric center to the lowest point on the swing arc at the time of maximum compression.

Side: The perpendicular distance between the target line and where the trajectory crosses a point that has the same elevation as where the golf ball was launched.

Side Total: The perpendicular distance between the target line and the golf ball’s calculated resting position.

Smash Factor: The ratio between the measured ball speed and measured club speed.

Spin Axis: The angle relative to the horizon of the imaginary line that the golf ball rotates around and is measured after separation from the club face.

Spin Loft: The angle between the direction of the club head’s movement and the club face’s orientation at the time of maximum compression.

Spin Rate: The rate of rotation of the golf ball about the imaginary line the golf ball rotates around measured immediately after separation from the club face.

Swing Direction: The angle between the base of the plane created by the club head’s geometric center movement and the target line.

Swing Plane: The vertical angle between the plane created by the club head’s geometric center movement and the horizon.

Total: The straight-line distance between where the golf ball was launched from and its calculated resting position.
