Club Path
The horizontal direction the clubhead is moving at impact, relative to target.
Directional ControlCurvature
The amount the ball curves in flight from start line to finish.
Directional ControlCarry Distance
How far the ball flies through the air before first landing.
DistanceCarry Side
How far left or right of the target line the ball lands at carry.
DistanceCarry Time
The time elapsed from impact until the ball lands at its carry distance.
DistanceCarry Deviation Angle
The angle between the target line and where the ball lands at carry.
DistanceClub Speed
How fast the clubhead is moving at impact, measured in mph.
Club DataClosure Rate
How fast the clubface is rotating closed at impact, measured in degrees per second.
Club DataCompression
How much the ball deforms against the clubface at impact.
Strike QualityD
Dynamic Loft
The actual loft of the clubface at impact, which differs from the club's stated loft.
Launch ConditionsD-Plane
The 3D plane formed by club path and face angle that determines ball flight.
Directional ControlDescent Angle
The angle of the ball's downward path as it approaches landing.
DistanceDynamic Lie
The lie angle of the club at impact, which may differ from the static lie angle.

L
Launch Angle
The vertical angle at which the ball leaves the clubface.
Launch ConditionsLaunch Direction
The horizontal direction the ball starts relative to the target line.
Launch ConditionsLanding Ball Speed
The speed of the ball when it lands, after decelerating during flight.
DistanceLanding Angle
The angle at which the ball descends when it lands.
DistanceLow Point
Where the clubhead reaches its lowest point in the swing arc relative to the ball.
Club DataLast Data Point (Length)
The distance down the target line where the ball was last tracked by the radar.
DistanceLast Data Point (Side)
The lateral position of the ball when it was last tracked by the radar.
DistanceLast Data Point (Height)
The altitude of the ball when it was last tracked by the radar.
DistanceLast Data Point (Time)
The elapsed time from impact to when the ball was last tracked.
DistanceM
R
S
Smash Factor
The ratio of ball speed to club speed, measuring energy transfer efficiency.
Strike QualitySpin Rate
How fast the ball rotates around its axis, measured in revolutions per minute (RPM).
Launch ConditionsSpin Rate Type
Indicates whether the spin rate was directly measured or calculated from other data.
Launch ConditionsSidespin
The sideways rotation of the ball that causes it to curve left or right.
Launch ConditionsSpin Loft
The difference between dynamic loft and attack angle, which determines spin rate.
Launch ConditionsSpin Axis
The tilt of the ball's spin axis, which determines curvature direction.
Launch ConditionsStart Line
The initial direction the ball travels immediately after impact.
Directional ControlShaft Lean
How much the shaft is leaning forward or backward at impact.
Club DataSide Deviation
How far left or right of target the ball finishes.
Directional ControlSwing Plane
The angle of the club's circular path relative to the ground during the swing.
Club DataSwing Direction
The horizontal direction the club is traveling at the bottom of the swing arc.
