So imagine a ball down there on the ground on the plane. The sweetspot is traveling down and out and forward ON-PLANE. (Remember the a vertical plane would only have DOWN and UP. A horizontal plane would only have IN and OUT). Since we are on an Inclined Plane the clubmoves in 3 dimensions (Down, Out, and Forward ALL ON PLANE).

You are correct that - The club travels on a 2 dimensional inclined plane but in reference to the horizontal plane (the ground) the club travels in 3 dimensions. You are correct that when refering to the vertical and horizontal planes with reference to the horizontal plane these planes will have only two dimensions.

You are incorrect that - The vertical plane has Upwards and Downwards as its two dimensions because unfortunately those two are the same dimension - just think of a piece of paper with an x and y axis. The club can move upwards and downwards (one dimension) but it can also move forwards and backwards (two dimensions).

So imagine the club and sweetspot traveling down and out on plane and then touching the ball. Through that point Homer drew a line parallel to the ground from the Impact Point and named it the Impact Plane Line.

A tip - if you are going to tell the existance of a geometrical line you should say exactly how to draw that line. What your saying here is correct but incomplete because just stating a line goes through a point parallel to the ground without referencing that this line is on the face of the inclined plane to establish its forward direction isn't helpful.

The club and its sweetspot CONTINUE Down and Out ON PLANE AFTER IMPACT POINT UNTIL THE SWEETSPOT REACHES ITS LOWEST POINT----OPPOSITE THE LEFT SHOULDER THE CENTER OF THE STROKE.

Actually, no it doesn't. This would be true if the left shoulder was stationary, however in the golf stroke the left shoulder is moving in its own little orbit that contains an upwards direction and this brings the low point backwards somewhat.

I would of let this slide if you had said "for concept purposes" like you did earlier but this holds no such disclaimer.

From the lowest point Homer drew a line and called it the LOW POINT PLANE LINE. For an iron shot the Low Point Plane Line is actually UNDERGROUND. So ALL STROKES SHOULD BE DRIVEN THROUGH IMPACT POINT AND CONTINUE DOWN AND OUT ON PLANE THROUGH LOW POINT.

This would be correct assuming the sweetspot gets underground which if it does your probably in trouble. The clubhead is bigger than the sweetspot you know .

After low point since the arms are connected to the shoulders the club begins to trave UP AND IN ON PLANE . . . but he effort is still down.

Again misquoting the book and/or misunderstanding the concept, the effort is not downwards in relation to the horizontal plane but downwards in relation to the inclined plane.
