I don't know if Yoda cares about the D-Plane. His specialty is teaching someone to swing a club. Yoda already knows that when the Golf Ball is properly struck, "The direction of the ball will always be practically at right angles to the Clubface and square to the leading edge of the Clubface at separation, unless there is enough time and speed for the Venturi Effect to alter it when scattered vectors have introduced a non-vertical spin."
It's not a big deal.
The "Old Ball Flight Laws" is an advertising campaign invented by Trackman to sell their machine. They weren't "Laws" at all. The "New Ball Flight Laws" are part of that advertising. They aren't laws either. The first stated that Initial Ball direction was mostly the result of Clubhead Path, and the later claims that initial Ball Direction is more a matter of Clubface orientation.
Earth-shattering? It is for Trackman. This is "Science"? Really? These are "New Ball Flight Laws"? You're kidding me. These are Advertising campaign slogans.
Both sets of these fake-Laws are based on the "False-Assumption" that "virtually-all" of the Ball Spin is created by the Ball rolling up the face of an inclined striker. That may be true for a Hollow Ball, like a Ping Pong Ball, but not for a Solid Golf Ball.
The following values are calculated and are posted as such on the Trackman web site.
Dynamic Loft*
Spin Loft*
Face Angle*
So, the entire Clubface alignment at Impact is calculated from Ball Flight Data.
Here's an written "Test" example: We know the Path of the Clubhead, Clubhead Speed, Ball Path and Spin. "Solve for Face Angle".
I'm not the only one that sees a problem with that.
