Another thing to consider is the height of the strings above the
soundboard - on a modern "classical" guitar, the height is much greater
than on a typical renaissance (or baroque) lute, so putting the little
finger (pinky) down makes no sense. I think Sor did it, but he had a
different guitar.
Tongue-not-entirely-in-cheek: if you want to talk about "inefficient"
technique, just look at the horrific bend in the wrist which is
considered normal on the (classical) guitar, and causes all kinds of
problems. Unfortunately our greatest expert has just passed away, and
can no longer add his voice....
