[C320-list] Holding Tank Vent

According to my owners manual ('98), it shows the holding tank vent exiting into
a deck stanchion. The stanchion has a small hole (1/8" +/-) through which the
tank vents. I also have, what appears to be, an overflow vent located in the
hull just below the holding tank pump out deck-fitting. Is this also acting a
vent for the holding tank ? The reason for my question is the Feb '12 article
in Practical Sailor that says holding tanks should have at least a minimum 3/4"
vent to have an effective bacterial reaction. Now maybe in '98 this
installation was acceptable but now ? If my vent is only the 1/8" hole in a
stanchion, maybe I should go back to using bucket. Knowing our group, I'm sure
someone out there can give me the poop on this fragrant issue (I know, pretty
bad puns).
