Understanding Golf Data Parameters

Introduction to Golf Parameters

Golf Data Parameters – In the world of golf, data analytics are becoming increasingly important. Whether you are a player, coach, or analyst, understanding golf data parameters can provide valuable insights into performance and strategy. This blog post will define some key terms that are essential for interpreting golf statistics effectively.

Key Data Parameters Explained

Full Swing Data Parameters

Club Speed: The linear speed of the club head’s geometric center just prior to the first touch with the golf ball.
Attack Angle: The up or down movement of the club head’s geometric center at the time of maximum compression.
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.
Club Path: The in-to-out or out-to-in movement of the club head’s geometric center 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.
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.
Swing Plane: The vertical angle between the plane created by the club head’s geometric center movement and the horizon.
Swing Direction: The angle between the base of the plane created by the club head’s geometric center movement and the target line.
Low Point: Distance from the club head’s geometric center to the lowest point on the swing arc at the time of maximum compression.
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
Dynamic Lie: The angle of the lower portion of the shaft relative to the waterline at impact
Ball Speed: The speed of the golf ball’s center of gravity immediately after separation from the club face.
Smash Factor: The ratio between the measured ball speed and measured club speed.
Launch Angle: The vertical angle the golf ball takes off relative to the horizon and is measured immediately after separation from the club face.
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.
Launch Direction: The horizontal angle the golf ball takes off at relative to the target line and measured immediately after separation from the club face.
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.
Height: The maximum height or apex of the trajectory measured relative to the elevation at which the golf ball was launched.
Curve: The horizontal side movement perpendicular from the launch direction to the carry side
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.
Carry: The straight-line distance between where the golf ball was launched from and where it crosses a point that has the same elevation.
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.
Total: The straight-line distance between where the golf ball was launched from and its calculated resting position.
Side Total: The perpendicular distance between the target line and the golf ball’s calculated resting position.
Swing Radius: Radius of the swing arc – measured at knee height until just before impact, i.e. the club trajectory from 8 pm until impact, and then fitting a circle to it and measuring the radius. Swing Radius can be used as a measure when trying to maximize power generation in the swing or to optimize the club trajectory for pitch and chip shots.
Max Height – Distance: The distance at which the ball reaches its maximum height – Slightly different than the apex which represents only the maximum height
Low Point Height: The relative vertical distance of the club head position from just before impact to where the swing would bottom out if there was no interaction between the ball or the ground.
Low Point Side: The relative horizontal distance measured perpendicular to the target line of the club head position from just before impact to where the swing would bottom out if there was no interaction between the ball
D Plane Tilt: It is the tilt of the D Plane relative to the plumb line. If face-to-path is zero, D plane tilt will be zero.D plane tilt is the expected Spin Axis discarding any gear effect because of an off-center strike or other factors like ground contact of the club head during the collision with the ball, abnormal friction conditions, etc.

Putting Data Parameters

Club Speed: The speed at the club head is traveling immediately prior to the impact
Backswing Time: The time the club head is traveling away from the ball
Stroke Length: The distance the club head is pulled back from the ball in the backswing
Forward Swing Time: The time the club head is traveling towards the ball until impact
Tempo: The Backswing time divided by the Forward swing time
Dynamic Lie: The angle of the shaft relative to the waterline at impact
Face Angle: The direction the club face is pointing at the center-point of contact between the club and ball at the time of impact
Club Path: The in-to-out or out-to-in movement of the club head’s geometric center at the time of impact
Face To Path: The angle difference between the reported face angle and club path
Attack Angle: The up or down movement of the club head’s geometric center at the time of impact
Launch Direction: The angle the ball starts right or left in relation to the target line
Launch Angle: The vertical angle the golf ball takes off at relative to the horizon and measured immediately after separation from the club face

Bounces: The number of bounces on the ground during the skid phase
Skid Type – Sliding: Ball with constant deceleration during skid phase (no bounces, sliding on the ground)
Ball Speed: Initial ball speed immediately after separation from the putter face
Skid Distance: The distance the ball is bouncing/sliding until it starts to roll
Roll Speed: The speed at the point where the ball starts to roll
Speed Drop: The percentage drop in speed from Ball Speed to Roll Speed
Roll %: The amount of roll on the total putt distance
Entry Speed Distance: The straight-line distance between where the golf ball was launched from and the point of entry speed (1.68 mph)
Side: The total side distance from the target at the time the ball reaches the entry speed
Distance: The total distance in a straight line from the starting point
Effective Stimp: The speed of the individual putt, based on the average roll deceleration
Flat Stimp: The calculation of green’s general speed, based on the average roll deceleration of the individual putt
Elevation: The height difference from the ball’s starting position to the point of entry speed
Break: The total side movement from the ball’s launch direction, at the time the ball reaches entry speed
Slope % Side: The average horizontal inclination of the surface
Slope % Rise: The average vertical inclination of the surface
