Assume the entrants (72 of them) averaged 60 votes each...giving 4300 votes.
That leaves an amazing number cast by members who didn't enter.
I think the votes are counted by the number - i.e. if you give a story 5 points, it counts as 5 "votes" in the system. If the average score is in the 5-6 range, each person voting for all the stories contribute around 400 votes (I seem to have contributed 388), indicating that 75-80 "full votes" have been cast (a "full vote" being a person voting on all the stories). Not all votes are full, some authors have multiple entries, and some authors may not vote at all, but I would still guess that the number of non-author votes is rather low.
