Shot data

Pick any number to see what it measures and what changes it. Start with the one you care about most, then connect them to see why each shot flew the way it did. Judge any number over 10 to 20 shots, not a single swing.

Near the tour average: enough spin to hold the ball up, not so much that it balloons.

Driver: 167 mph ball speed, 10.9° launch, 2,686 rpm spin (PGA Tour averages). An illustrative model, not measured flight: still air, and roll is an estimate for a firm fairway.

Choose a metric to read what it measures and why it matters. The lab above switches to that metric and shows it from the angle that makes it clear, so you can move it and watch how the shot changes against a tour average.

Club delivery

What the club is doing at impact: how fast, which way and at what angles.

Club Speed, Attack Angle, Dynamic Loft, Club Path, Face Angle, Face to Path, Spin Loft, Dynamic Lie, D Plane Tilt

Strike

Where the ball meets the face, and how well that turns club speed into ball speed.

Impact Height, Impact Offset, Smash Factor

Ball launch

How the ball leaves the face. These five numbers decide the whole flight.

Ball Speed, Launch Angle, Spin Rate, Launch Direction, Spin Axis

Flight results

Where the ball goes: how far, how high, how much it curves and where it stops.

Carry, Total, Height (Apex), Max Height Distance, Landing Angle, Curve, Side, Side Total

Swing geometry

The shape of the swing around impact, which sets up the club delivery numbers.

Swing Plane, Swing Direction, Low Point, Low Point Height, Low Point Side, Swing Radius

Putting data

These metrics describe stroke mechanics, launch, skid and roll behavior, and green interaction.

Club Speed (Putting)

Putter speed immediately before impact.

Backswing Time

Time spent moving the putter away from the ball.

Stroke Length

How far back the putter travels in backswing.

Forward Swing Time

Time from transition to impact.

Tempo

Backswing time divided by forward swing time.

Dynamic Lie (Putting)

Shaft lie at impact during putting stroke.

Face Angle (Putting)

Putter face direction at impact.

Club Path (Putting)

Path direction of putter through impact.

Face to Path (Putting)

Difference between putter face and path.

Attack Angle (Putting)

Up/down movement of putter at impact.

Launch Direction (Putting)

Initial left/right start direction of the putt.

Launch Angle (Putting)

Initial vertical launch of the putt.

Bounces

Number of bounces in the skid phase.

Skid Type (Sliding)

Skid profile with constant deceleration and no bounce.

Ball Speed (Putting)

Initial ball speed off the putter face.

Skid Distance

Distance from launch until true roll starts.

Roll Speed

Ball speed when pure roll begins.

Speed Drop

Percent speed loss from launch to roll start.

Roll %

How much of total putt distance is true roll.

Entry Speed Distance

Distance to standardized entry-speed point.

Side (Putting)

Lateral offset from target at entry-speed point.

Distance (Putting)

Straight-line distance traveled by the putt.

Effective Stimp

Putt-specific speed based on deceleration.

Flat Stimp

Estimated general green speed from deceleration.

Elevation

Height change from start to entry-speed point.

Break

Total sideways movement from launch line.

Slope % Side

Average horizontal surface inclination.

Slope % Rise

Average vertical surface inclination.
