Do you think the term "plane shift" is apt when what most /all people do ( including Leadbetter - hence your X classification) is a "plane drift"?
Plane angle can readily be defined at 4 points in all swings.
1. Address
2. Left arm horizontal to ground
3. Top/end of backstroke
4. Impact
plus maybe Follow through/ both arms straight.
Most golfers ( I would argue all golfers) drift planes between these positions. During drift the butt/end of club rarely points at target line unless the drift happens rapidly around clubshaft horizontal ( and therefore ideally parallel to plane line).
Leadbetter people basically are double shifters - categorised by their address / impact location and top/end of backstroke positions. They may drift a bit more than others off TGM plane at left arm horizontal but 90 % of people drift not shift!
Why the left arm horizontal as a definition point?
If we are talking about the club being on plane, I would have expected the definition points, a more universal set, would be the club, not the left arm....

Yup totally agree here Martee
Infact stopping at any point on the backstroke or downstroke the club should be on a plane. Predefined points is position golf, geometrical alignments is alignment golf.
Interestingly leadbetters procedure is an underplane shoulder turn takeaway which then shifts to another steeper offplane plane that also passes between through two onplane planes at parallel...can't see the logic myself . Now on the downstroke he wants you to shift from that offplane plane to another offplane plane parallel above the hands only plane before getting to the elbow plane... ok then.....
I like what Moe Norman said about him "artificial strokes for artificial folks"....

All due respect..I believe in the 4th edition the left arm had a delivery line designation..2-J-3..
For a guy who uses 10-6-D..this reference can be very useful...
