Yup, finally got it. Only took, well lets not go into that.

After talking with a number of people over the years, Phd's included, I finally get it.

1. The Sweetspot Plane is something you FEEL that you are swing on.

2. The Sweetspot Plane is not something you can draw on a picture, it is FEEL.

3. The True Plane Angle should be defined and Impact and then applied backward to photo when analyzing them.

4. The Clubshaft Angle is set at Impact Fix is the most likely and accurate line you can identify for see the Inclined Plane.

5. All of this HAS TO BE TRUE, else Homer's Plastic Plane as shown in all the photos would be invalid.

6. 10-5 supports this.

7. 2-F supports this in the definition of On Plane.

The Sweetspot Plane is just a Feel. Plane Boards wouldn't work, laser devices attached to the golf club shaft would be invalid.

That is not to say you can't identify it, but

a. It will always be flatter than the clubshaft plane
b. It is dynamic in that as the clubshaft is move to this plane (see 2-F description of On Plane) it will be changing

and I could go on...

Now if you all are going to say no to this, then I would like to see a series of pictures of a golfer is swinging on the sweetspot plane and at impact is in that position as well including showing that the Forearm is on plane while the clubshaft is not.. Cause you can't have a clubshaft on plane, a forearm on plane and call that the sweetspot plane and state that the clubshaft plane (defined by the clubshaft angle at impact or lie depending upon setup).

I wonder how many people really realize all the lines they are drawing are not the sweetspot plane.

Even Homer addressed part of the concern regarding lie angle in 7-6.

Feel vs Mechanical.....
