ABSOLUTELY . . . that is what is impacted no? The ball would always be on the impact plane line . . . low point plane line and impact plane line get farther apart as you move the ball more back. as a result the angle of approach (and angle of attack in 3D) become more acute with angle of approach being defined as the line that connects impact point and low point. . . low point plane line and impact plane line would be the same if the ball is struck at low point . . . this is the only time impact would result in a tangent . . . impact plane line would be above the low point plane line if the ball were struck after low point . . . but still be a chord and not tangent.

Thanks for that 12 piece.

Some follow up questions if you don't mind.

As I reread your reply and Lynn's reply, I get the impression that the impact plane line is the same as target line for a straight plane line strike from a square-square set-up.

Is that correct?

Secondly, where in this parallel line arrangement is the direction of the club head taken into account at impact? Surely, because the club head is still moving downward, outward and forward from impact to low point that the club path at impact is right of the impact plane line and the low point plane line.

If the face was square to the target at impact and the path is right of the target at impact, won't this ball draw?

If not, why not?

As always, Please forgive my lack of TGM terminology and understanding.
