I started this thread because this is a precision alignment and any arbetrary flap about or misapplication is bad.
These are some of the facts/considerations that
have gone into my thought:

1. The shoulder turn is around the spine.

Discussion?

For starters, #1 is not true even for a rotated shoulder turn. The spine is on the outside of the body and gets thrown around by the shoulder turn, however flat or steep.
