### Meeting duration as a function of the number of participants

My conjecture is that a meeting involving $$N$$ participants takes a time $$T$$ given by:
$T(N) \, \text{[in hours]} \, = \exp (N/\; 7) -1$This only applies to unstructured meetings (with no official hierarchy) and is fairly insensitive to the topic at hand. The time ranges from 20 minutes for $$N=2$$ to 4½ hours for $$N=12$$.

For any meeting larger than about ten attendees one should either designate a chairman or schedule a lunch break.
