Question about Launch H vs Spin Axis

[Jajaju]

I tends to fade my shot but typically launch the ball towards the target line then curve right( sometime I will say it's a slice and assumed it's because I have open club face)

But based on mevo+ data, it does rwgister many of those as fade shots. But I noticed some time I have right spin axis and some time left axis while launch H can be right or left with random combinations. I attached two sample shots(and they are decent ones, I have way worse ones as pull or push and in those cases, launch H and spin axis are both left or right)

This may be more a golf knowledge question but curious anyone can educate here.

Club face angle has the biggest effect on the H-launch angle of the ball. Spin Axis is the delta between club face angle and club path that describes the direction of curvature in the ball flight.

FS golf app also has definitions in the help section. both shots had right spin axis. guessing that the straight show was less offline compared to the fade shot?

H launch is the initial direction ball launches off the face which is influenced by club face being open or closed to target line. The spin rate or spin axis (Curvature) is influenced by path and face direction which determines the shot shape and how far ball lands left or right of target.
Say your swing is slightly over the top (left for a right handed golfer) and to get the ball back to target you would need some type of open to PATH face to get ball back to target. If the face is open to TARGET you will get a bigger fade or slice and ball will start/go further to right of target.

Based on your shot shape above it appears you swing slightly over the top with a club face slightly open to target line

This is trackman's examples of face angle relative to horizontal launch. These numbers are assuming neutral swing path and Center strike. Off center strikes cause the gear affect which can influence both side launch and curvature.

Launch Direction is the initial direction the ball starts relative to the target line (curvature does not influence this number)


A positive launch direction indicates a ball that starts right of the target and a negative launch direction indicates a ball that starts left of the target.

The larger the number, the more offline the ball has started (right or left). A zero launch direction means the ball started directly at the target.

Launch direction is reported in degrees and can be thought of in terms of push, pull, or straight. It is important to understand that launch direction does not describe the curvature of the shot, only its start direction.
For example, a ball with a launch direction of “-2.0 deg” will be 3.5 yards left of the target line at 100 yards and 7.0 yards left of the target line at 200 yards. Or a ball with a launch direction of -4.0 deg will be 7.0 yards left of the target line at 100 yards and 14.0 yards left of the target line at 200 yards. These examples simply use the launch direction to determine how far a ball would be offline at a certain distance. There is no curvature accounted for because curvature is not linked to launch direction.


Launch Direction Examples

@ 100 yards

• -1 degree = 1.7 yards left
• -3 degree = 5.2 yards left
• 2 degree = 3.4 yards right
• 4 degree = 7.0 yards right

@ 200 yards

• -1 degree = 3.5 yards left
• -3 degree = 10.5 yards left
• 2 degree = 7.0 yards right
• 4 degree = 14.0 yards right
