Angle of Approach Procedure Question
 

In a previous post Yoda once said:

"Hitters using the On Line (2-J-3) Arc of Approach Procedure Trace the same Plane Line as Swingers -- typically the Square Plane Line of 10-5-A. Again, assuming the Sweet Spot Plane (2-F) -- as opposed to the Clubshaft Plane -- the Impact Point Plane Line lies on the Target Line, i.e., they are dually represented by the same single line.

Hitters using the Cross Line Angle of Approach Procedure do not visually Trace the Square Plane Line that lies atop the Target Line. Instead, they visually Cover the Closed Plane Line of 10-5-E whose Base Line actually crosses it (2-J-2)."

Help me understand this. How can you visually cover a line (in this case the Closed Plane Line of 10-5-E) since the club head is moving in an arc? I understand tracing a plane line, but I don't understand how you can cover a plane line. Any expansion on this would be appreciated.

These lines are not parallel. You cannot cover a parallel line with the clubhead, only Trace it with pp3. A Hitter with a ANGLE of Approach can cover this angled crossline Delivery Line with the clubhead as it crosses over the Plane Line or target Line to the ball. You can never trace an Arc, either.

You said it here: "Instead, they visually Cover the Closed Plane Line of 10-5-E whose Base Line actually crosses it (2-J-2)."

Angle of Approach Procedure Question
 

Sorry to be obtuse, but how can you visually cover the Closed Plane Line? If cover a plane line means that the clubhead is directly over the plane line, how can that occur if the clubhead is moving in an arc and a plane line is straight?

The club head does not cover the plane line but covers the alternate target line (roughly 11 degrees out toward right field).

another way of comprehending is not covering but rather pointing at the base extension of the plane line....kinda like if the shaft extended as you go back...it would go from say 45'' long at startup too 60'' a couple of feet in the backswing, does that make more sense? that way if it extended for real, even if you are in an arc, the extension would still be covering the line.

I can understand that you could be tracing the alternate plane line, but as I remember Homer specifically refers to the clubhead covering the alternate plane line and he usually meant what he wrote. I didn't see how the clubhead could ever cover any plane line except maybe if the club was on a completely vertical plane.

(almost) vertical
 

You're certainly on the right track. I've spent many hours studying this very subject.

I had problems reconciling the logical arguments and statements about this subject. My major concerns were with the seeming contradictions with 1-L. So, I knew I was treading in unchartered territory.

The Angle of Approach Procedure is a 10-5-E, closed Plane Line. This Plane Line is a line that is VISUALLY covered by the clubhead blur. The reason that the clubhead can VISUALLY cover and still move in a circle, per 1-L #9 is: the steepness of the plane.

When you're riding a bike and you look down at the tire, you see the straight line that the tire covers (wheel track). When you're watching someone ride beside you, you're seeing the side of the wheel (wheel rim). It's all about VISUAL perspective.

When Impact and Low Point are kept as two constant points on a 10-5-A Plane, a second Plane could pass through the same two points and be much more vertical. As the steepness of the new Plane approaches the steepness of the eyes (compared to the Turned Shoulder Plane with the eyes above it), it appears to be a straight line blur of the clubhead.

It's something that can be shown in a couple of minutes with two circles. But, it's a little hard to put into words.

A Geometric Understanding
 

A video is worth one thousand words.

Coming soon to a computer near you!

:)

Don't we have a video of that? I've done over 75 videos for this site and seem to recall a session with you and the hulu hoop.

Before anyone gets any ideas, it wasn't around the Nukesters hips!
It was around his head. :laughing9

It may be in my private lesson stock.

I have seen this demonstrated too but I don't think it was in a video though (I think Ted showed the hula hoop to Martee and I when I was down at the Swamp) When demonstrated it was like ahhhh........I get it now. A very simple setup that explained a lot of things.
