In my opinion, the following rule of thumb is reasonable.
1 path is enough for a site/enterprise that shuts
down its services evenings and weekends.
2 paths is enough for a site/enterprise that provides
a 24 hour, 7 day per week service.
3 paths is enough for a population center with under
a million inhabitants.
5 paths is enough for a population center with over
a million inhabitants.
And a very few population centers such as New York,
London, Tokyo, and Cheyenne Mountain should probably
have more than 5 paths.
