What are you trying to get at? I have no idea.
In a general sense, the flattest normal plane at impact is dictated by the club - it is the plane that allows the lie of the club to be "normal" (sole of the club to be horizontal to the ground) at impact, so that the the heel of the club doesn't hit the ground first.

2-D Pictures taken off plane conceal the truth.
Best way to truly understand the swing plane is build yourself a swing plane as in the book. Set the plane per the photos in 10-6 and swing away.
You may find it difficult to interpret 2-D DTL images in terms of swingplane, but I don't. I realize that a perfectly accurate assessment cannot be established from a 2-D DTL image that is off-axis, but it can be close enough to justify general conclusions eg. establishing that SG and TW's clubshaft comes down on a shallower plane than the TSP in the mid-late downswing, and that SG drops his hands/clubshaft down to the elbow plane early in his downswing action. Look at SG's third image - when his hands are at belt level, when his clubshaft cuts across his lower biceps and when his clubshaft cuts across his mid-lumbar spine. Adopt that position when facing a side-mirror - it is incontrovertible that your clubshaft will be just above the hand plane, and close to the elbow plane, at that time point.

Why look at pics? I have a swing plane. I can locate the elbow, TSP, hand and turning shoulder planes. I can double shift, triple shift and quadruple shift planes.
Thanks. Homer described a triple shift in 10-7-D but he didn't include your quadruple shift variation in his book. I would be very interested in seeing a visual demonstration of your quadruple plane shift swing.
