I wrung out the debate on uunet (on rec.aviation.piloting, and rec.aviation.aerobatics).     
                                                    
                                                     
I managed to provoke several dozen responses and was ultimately called an idiot in an email
exchange from a well known retired test pilot.   Standard fare for a newsgroup interaction I suppose.

However, one profound suggestion was to reach out to Rich Stowell.   He is the evangelist
for the P-A-R-E recovery acronymn. 

Power (to idle)

Ailerons (to neutral)

Rudder (against the spin)

Elevator (briskly forward to break the stall). 

I must say he drafted a very thoughtful response to me in a direct email.   In so doing he affirmed 
what most of the denizens of rec.aviation polled (including the test pilot).  There must be two ingredients
to spin:   A stall, and yaw. 

The only conclusion I can offer to this essay is to point to his web site, and his book(s):

He articulately explained that the inclinometer is not a precise indication of coordinated flight and that
some form of yaw is a necessary ingredient to the spin.

It really is a deep subject and I would steer anyone to his texts (he sent even sent me PDFs of the relevant
sections) or to the Aerobatics text by Williiam Kersher:
