Thread: Finally....a "D" Plane pic.....by Manzella

That'a gonna be a hard up and down from back there.

Great visual explanation.

how is this different from the concept of clubface orientation and path? what is the third point in the plane and how does it make a difference? Is that slanted orange line supposed to be parallel to the end of the ball curvature?

How do real golfers use this?

Well....

The old PGA "Ball Flight Laws says that the ball would start on the PATh and curve to the face.

Wrong.

The ball starts between 70 and 90% toward the WHOLE FACE (including loft) and curves AWAY from the path.

For starters, everyone can stop trying to swing WAY inside-out.

Brian, can you do us a big favor and show how the ball would go based on the old PGA "Ball Flight Laws? I think that would help some. Thanks

Just to get the straight in my simple mind...


Mr Sneads path would be "y" Yards right

Mr Sneads clubface would be aimed about "x" yards right at impact/separation

Ball would start about 70-80% toward "x" yards right and curve left "z" amount to finish left of target.

Is there anyway of working out how much to the left it would go?

Are all computer launch monitors configured with "old" ball flight laws?

Here is a true Hogan story . Hitting balls perfectly he all of a sudden hit 2 pull draws in a row and promptly went back to the clubhouse and locked himself away for a few hours not to be disturbed. Upon returning from the deep session of contemplation he was asked what was the answer . All he said was the face was closed.
See its no big deal is it and Hogan didn't need all the fancy gadgets to figure out the problem

The Gary Wire inspired, old PGA Ball Flight "Laws" result:

The be fair, the PGA did NOT use the path or clubface in 3-d, like the D plane.
