OK what's a Fair Funcle? And why are trying to estimate mean (average) time between posts?
Some[busy]body or another posted the Fair Funkle rules a while back.
They're more stringent than ordinary funkle rules - 5 posts in a row from the same poster.
IIRC, in order for a funkle to be a fair funkle, the thread has to be a live thread, the intention to funkle has to be announced in advance, and the qualifying posts can be no more frequent than one every 20 minutes...
