... I believe that in the end Homer had a preference for the TSP and not shifting down to the lower elbow planes.

Yes, My good neighbor.

I did not see any explicit Ref. to TSP only implicit Ref to "more upright" plane. And I do see explicit Ref. to Elbow Plane with an implicit range of "compensations" to accommodate an EP as it is established off the "more upright" planes.
I cannot remember where Homer Kelley stated a preference for a component variation beyond the geometry for its accommodation.
But I could have missed it so if anyone has a specific Ref. I would appreciate seeing it.

I do see 7-23 par. 3 as significant alignment discussion.
