Can't answer your question specifically. However, my outfit, a larg(ish) A320 operator, had a policy of using the aft cargo compartment as priority. FWD compartment was hardly ever used - only on rare occasions when there was too much baggage to fit in the aft hold.
Resultant T/O C.G. Position was usually between 30-33% MAC.
Recently the policy has been changed and now we are using mainly the FWD compartment (this is supposed to speed up the loading process). The resultant T/O C.G. values are now usually in 26-28% range. Plenty of margin to spare either way...
