How does Trackman account for ground angle?

[Petunia Sprinkle]

Having recently had my universe shattered by the notion that it is clubface angle and not clubhead path that primarily determines initial ball direction, thanks to larrybud and b.helts, I started reading a bunch of Trackman stuff (in addition to experimenting with a wedge and ping pong balls in my bonus room). I haven't come across anything about the angle of the ground upon which a ball is lying (does it just assume a flat lie?). I'd be curious to see what the real best way to deal with uneven lies, particularly ball above feet, would be. I have always played ball above to hook more, so I'd aim a little right, put the ball further back in my stance, and use less loft. Now, I wonder if it might be better to aim right and swing straight, putting a little cut spin on it.

 

Btw, this Trackman stuff has fried my brain (I even tried to get a drink of water out of the back door knob). I've always been a very straight hitter despite thinking I was set up to draw the ball. I would close my stance, aim the clubface at the target and swing what should've still been in to out, even though I knew I was always coming over the top. My guess, now, is that I was coming over the top more than I had thought. The info explains why some things worked (even though I thought it was for a different reason) and why other things didn't work. Sucks it's raining.

That is why there is no substitute for hands-on experimentation.

(Yeah, that doesn't quite sound right but screw it)

uneven ground changes the lie angle of the club which in turn changes the orientation of where the club face points when you address the ball. Not really a Tracknan thing.

Even on flat ground, the angle of the ground for a flatter lying club would be different than a more upright club. Though, that probably doesn't matter to one golfer just comparing his own results.

Radars just calculate the face in relation to a target. Lie angle changes affect the face angle regardless of the ground. Upright points it more leftward and flatter vice versa. It does matter because if your clubs don't fit and lie angles are off you'll have a hard time starting the ball on the right line and if you get on a Tman the face angle calculation will be off even if you put a good move on it.

Due to the loft of the club face the ground angle effects a higher lofted club moreso than the lower lofted. And the curvature of the ball is due to the spin axis number (which is what Trackman accounts for) you can move to a different lie angle with a mobile unit and notice the drastic difference of the spin axis number as opposed to flat lies. Still possible to hit a straight shot just relies even more on the face angle and club path.
