**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 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.

**Club Speed**

The speed the club head is traveling immediately prior to 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.

**Launch Direction**

The angle the ball starts right or left in relation to the target line.

**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**

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.

**Effective Stim**

The speed of the individual putt, based on the average roll deceleration.

**Side**

The total side distance from the target at the time the ball reaches entry speed.

**Break**
