To the best of my knowledge, just like IV, IH etc, each time a person accesses the EDIG board, that's a hit.
For me, I visit 4 or other 5 hubs daily and return to EDIG, but 90% of my time is EDIG, plus might look in the morning and again at night.
So, I might be 5 hits per day myself.
Wether the true # is 50/60/70%+ of 800???
On the IP comment, there are both static and dynamic IP's, so that enters into the picture.
It's a FWIW metric and that's all.
