I don't know.  I've seen some reconstructions in the past that were
inverted.

I've just pulled out a Qsp sc and without measuring it, just by
uncalibrated eyeball I'd say that the socket is roughly about 55% of the
way down from the top of the sc.  If you add the sternum to the vertical
height, maybe 45% of the way down from the top?

There's been some discussion that these 'lowwingers' have decreased
stability.  But I have 3 highwing airplanes and one lowwing.  The
lowwing is by far the most stable.  There are other factors that are far
more important to stability than the vertical location of the cg
relative to the shoulder articulation.
