It is not about Suspecting. The reality is that when an alternator slows down the possible level of voltage generated will decrease. It is just the way it works. The only voltage drop should be when you turn something on (then your regulator should return it back to 13.2. Should? Doesn't work by should. An alternator at normal idle speed will actually let the battery discharge instead of charging with all the lights, accessory, etc turned on.
That is with a new properly functioning alternator at proper idle speed. (actually if the system is functioning properly, the idle speed will increase when you start turning everything on but will let the output decrease enough to begin to sap the juice from the battery).

And no need to be sorry!
