ZERO° PATH, ZERO° CLUBFACE
Here are some terms you need to get right in your coconut:
Horizontal Swing Plane - Plane Line in "Golfing Machine" terms, the base line of a plane.
In general, this is the "direction" of your swing.
Vertical Swing Plane - Plane Angle in "Golfing Machine" terms, the pitch of the roof—so to speak.
Club(head) Path - The path of the golf clubhead—or if you like to think smaller, sweetspot—through impact, in 2D space relative to the ground...on the Horizontal Axis.
Because the arc that the clubhead travels on is so big—relative to the 3/4th of an inch to 1/2 inch that the clubhead is on the ball—this path is actually nearly a dead straight line.
Attack Angle - The path of the golf clubhead—or if you like to think smaller, sweetspot—through impact, in 2D space relative to the sky...on the Vertcial Axis.
True Path - A brilliant Manzella-ism
that is the actual path of the clubhead in 3D space. Think of it as a combination of Club(head) Path and Attack Angle.
Face Angle - Where the clubface is "pointing" in 2D space relative to the ground...on the Horizontal Axis.
True Clubface - A another brilliant Manzella-ism
that is where the clubface is actually pointing in 3D space. Think magnetic lie angle tool. Face Angle + Dynamic Loft + Delivered Lie Angle.
Dynamic Loft - The amount of "delivered" loft at impact. You can have a 60° wedge, but if you "de-lofted" it 10°, you had 50° of
Dynamic Loft.
Spin Loft - Delivered Loft minus Attack Angle. A 60° wedge, de-lofted to 50° of "Delivered Loft" hit 6° on the way down, would have 56° of "Spin Loft."
D-Plane A plane angle with three points, the ball, where the TRIE club face is pointing, and where the TRUE path is pointing. Most of the time, the TRUE PATh is on the bottom. The ball will start ~70-85% of the way to the TRUE CLUBFACE, and then curve—UP THE PLANE, toward the TRUE CLUBFACE, until gravity and (or) wind take it out of its journey.
Since the clubhead is striking the ball on the way down with an iron—approximately 6° with a 60° wedge, 5° with a pitching wedge, about 3° with a long iron—the clubhead is STILL TRAVELING
downward,
outward, and
forward on the face of the plane (Vertical Swing Plane).
So, wherever that "Plane" is pointing (Horizontal Swing Plane), the TRUE PATH of that clubhead will be down and out to that line.
With a Driver—which you do not want to hit on the way down, but you
can—when it is swung with a 45° Vertical Swing Plane (plane angle), the clubhead is traveling 1° out for every one degree down.
With a club swung at 60°—the club is moving ~0.56° out for every one degree down.
So....
Lets say you hit down 6° at 60° with a 5-iron.....you are also hitting "out" ~3.33°
And since 1° at 100 yards is about ~1.75 yards....
And you hit your 5-iron 185 yards....
You need to AIM and (or) SWING ~3.33° at 185 yards....which is ~
11.4 yards left of the target!
That will give you the bottom of the D-Plane on the target line, and you now have to have the CLUBFACE square to the target, or in this case 3.33° open to the "Plane Line."
Aren't you folks glad you have me?
