Great post 12 pc. You're very right about the fact that this info is not common knowledge, even to decent players, is is truly the difference between hacking and G.O.L.F.ing.

Something that has always puzzled me since first learning about these principles is this:

If the plane line is parallel to the target line then what kind of dimensions are we speaking of when discussing across, or out?

Notwithstanding the variances for club length and arc length, there ought to be a known value (ball-park) for how far out past the target line the clubhead travels.

Outwards is the direction where your feet are pointing (90 degrees to the plane line). When mixed with the downwards direction in the downstroke you get the resultant direction of going forward. The plane line co-ordinates these directions.
