The Practically Mandatory, in both directions, Combinations for procedures and delivery lines says:

1. The visual true arc and orbiting clubhead line with Circle Path.
2. The visual angle of approach line with drag loading.
3. The basic aiming point line with drive loading.
4. The left arm swing plane line, flip release. (pivot-controlled procedure) (The first I'd heard of this left arm swing plane line.)

And then it says,
"Drive loading calls for the angle of approach."
"Drag loading calls for the arc of approach.....which requires circle path."

(It says nothing about axis tilt enabling the line paths and the angle of approach delivery line, making it an option for drag loading.)

So the listing of Combinations and the discussions of lag loading characteristic combinations are conflicting.
Usually we say swingers use arc of approach, hitters use angle of approach and either can use Aiming Point or trace the basic geometric plane line.

Comments on the apparent Notes conflict? Mistranscribed, or updated in further revision?

Also, what is the significance of the clubhead moving above plane with momentum after impact with the angle of approach for swinging?
That's apparently been omitted in the 7th edition.
What compensation is required? Automatic? Is it a drawback?
