We will assume that my wife and I are (more or less) average. We routinely go one week between dumps with a 40-gallon black tank. So not more than 20 galons per person per week seems like a reasonable figure for black tank usage.
(I say "not more than" because our tank is unlikely to be completely full when we dump.)
Even though we follow recommended practices (plenty of water, dump only when full), we managed to have a toilet blockage recently. (It was the fifth-wheel's eleventh year of use.) We put a hose down the toilet with nozzle set to high pressure to break up the obstruction. (We discarded the hose and nozzle, of course.)
