I don't assume that at all :) If you didn't already, have look at the
link.  I was talking about notation of the normal everyday contemporary
tempered system where there is no pitch difference between Ab and G#. But even
in a just system, any difference between them depends on the system itself,
the key, and whether you choose to call them that. I've never heard anyone claim
that C is sharper than B#, although in the key of E the relationship would be
the same. 

AIUI there is any number of whole number ratios which fall between seven and
nine tempered semitones above the fundamental (to take your example), and in
C, any one of them could be called either Ab or G# depending on the key
signature or other context. IMHO, that's the aspect that could benefit from a
simplified representation.

To the OP, I'm deeply sorry!
