and yet, I only stock AF 15 with no MC, and I get the same $'s, grade for grade (5.0 and below only so far) for both
This may be true on an anecdotal basis, but it hasn't borne out in public auctions, not even this one, where there were like-graded copies of each offered up at the same time. And the 7.0 SC 4 that sold is even further off from even the weakest AF 15 sale in grade.

there's separation above 5.0 (as stated ) but auctions only represent a fraction of sales. There's nothing anecdotal about actual realized sales
