Premium and Elite Measures
Herewith is a brief definition of measures found within the “Premium” and “Elite” version of the Vertex Golf App / System.
Dynamic Aim
Face Angle position prior to any significant movement in the direction of the back stroke.
Key Focus:
If your intention is to aim square with your ball to target line, you are looking to be as close to 0° as possible. 1° of error would be approx. the edge of the hole at 10ft.
Static Aim
Face Angle position before any trigger movement within the stroke.
Key Focus:
If your intention is to aim square with your ball to target line, you are looking to be as close to 0° as possible. 1° of error would be approx. the edge of the hole at 10ft.
Path Direction (Relative to Target)
Path direction is the direction the sweet spot of the putter head is travelling through impact, relative to your intended target.
Key Focus:
0° – 1° “In-to-Out” is considered optimal, anything outside of 4.5° is considered to have an adverse effect on the golf balls direction.
Gear Effect Twist
Measure of how much the putter face twists during impact due to an off centre strike. If the club face twists significantly closed on the toe, this suggests a heel strike occurred. I the club face twists significantly open at impact, it suggests a strike towards the toe.
e.g. If you get a result which says (1.5° twist from the Toe), this suggests the club twisted closed, probably due to the ball being closer to the heel of the club.
e.g. If you get a result which says (1.5° twist from the Heel), this suggests the club twisted open, probably due to the ball being closer to the toe of the club.
NB: Results can vary slightly depending on the style of putter used, in particular to the CG (Centre of Gravity) location and MOI (Moment-of-Inertia) characteristics of the putter.
Key Focus:
Gear effect twist can affect both ball direction and distance control. To improve either of those parameters consider this metric.
Takeaway Torque
Is the difference between the Static Aim position and the Dynamic Aim position. The Amount of movement in the stroke, before a significant movement in the direction of the back stroke.
Lie Angle Address
Angle of the shaft relative to its calibrated position in address position.
Key Focus:
Aim to keep your Lie Angle within 0-2°
Lie Angle Change
The difference between the Lie Angle at Address and the Lie Angle at Impact.
Key Focus:
Aim to keep your Lie Angle within 0-2°
Shaft Lean Impact
The amount the shaft is leaning towards the target at the moment of impact relative to its calibrated position.
Key Focus:
Aim to keep your shaft lean between 2° forward and 1° back.
Shaft Lean at Address
The amount the shaft is leaning towards the target at address relative to its calibrated position.
Key Focus:
Aim to keep your shaft lean between 2° forward and 1° back.
Shaft Lean Change
The difference in shaft lean to the target between address position and impact.
Key Focus:
Aim to keep your shaft lean between 2° forward and 1° back.
Loft Angle Address / Impact / Change
Std. Default Loft is set at 3° up from a 0° Shaft Lean (Editable in future).
Key Focus:
Aim to keep your Loft Angle between 0° and 4° up at Impact.
Face Change 10cm from Address
Measures the Face Angle Change from Address (Start) to roughly 10cm in to the backstroke.
Face Change 10cm before Impact
Measures the Face Angle Change towards Impact from roughly 10cm before impact in the forward stroke.
Face Change 10cm after Impact
Measures the Face Angle Change After Impact to roughly 10cm in to the follow through.
Club Head Acceleration
Club head acceleration is the rate of acceleration of the club head at the moment of impact. This could be negative (deceleration) or positive (acceleration).
- Acceleration will produce a positive change in speed.
- Deceleration will produce a negative change in speed.
In-Plane Rotation Back
Is the amount the shaft angle (shaft lean) has rotated in the backswing
In-Plane Rotation Forward
Is the amount the shaft angle (shaft lean) has rotated in the forward swing
