Your whole analysis falls apart if Djoko's RA does not turn out to be 65. If Greg Raven measured 51, what make you think otherwise? Any indirect evidence?
Also, 355 to 370 is a huge range when it comes to SW (whose unit is not grams, BTW).
I would say that the first spec is to have a strung weight greater than 12 oz. The balance used to more head-light in previous eras of graphite, but today's favored setup seems to be 4 or 6 points HL for more plowthru.
