Maximum Compression

[KevCarter]

Just a note that the folks at TrackMan have been trying to simplify the language and have changed a couple of definitions to make it easier to discuss without learning new terminology.

Swing plane (formerly vertical swing plane): a measure of how
vertical the swing is, where a high value represents a very up and
down (steep) swing plane and a low value a relatively flat (to the
ground) arc. More technically, it is the angle made between the
ground and the plane of club head trajectory
at the bottom of the swing arc.

Swing direction (formerly horizontal swing plane): the orientation
of the swing arc, relative to the target line, where positive
means to the right, negative means to the left. More technically, it
is the horizontal direction the club head is traveling in at the bottom
of the swing arc

Launch direction (formerly horizontal launch angle): the initial
direction of the ball relative to target line. Positive means to the
right, negative means to the left

Hopefully this will help in our understanding as the new terms are very much in line with our studies IMHO.

Thanks, Kev. I don't care so much for those "new" terms. Perhaps TM bowed, overly so, to customer pressure? I think I would go with

Horizontal Plane Angle
Vertical Plane Angle
Horizontal Launch Angle
Vertical Launch Angle
Horizontal Path Angle
Vertical Path Angle


Even simpler, no?

They're still wrong. Why don't they get their own terminology instead of bastardizing another for their own Corporate GREED?

I have no opinion. I simply shared what TrackMan posted in their newsletter.
