246 in 4th
shhh - I'm voting down in the basement - I was in the barn earlier, and my laptop before that. I think I finally figured out how this thing works - CJ, or whoever correct me if I am incorrect.
It updates every hour, but not at the same time. You can tell when the last update was by scrolling to the bottom of the page and it will list when. As I am writing this which is 3:51 Central Time at the bottom it says
"Rankings are updated every hour
Last Updated: 6-16-12 1:40pm"
As to when during the hour it updates seems to be based on some kind of random number generator scheme used in the coding. I have spent a lot of time watching this thing over the last several months (sad, but true), and have noticed no specific pattern. The one time I "watched" it update on my phone and blamed it on our slow dsl was just lucky.
And it seems to recognize by mac address, not just IP, 'cause we have a network on our little farmette, with six desktops, 4 laptops, one netbook, and two smartphones. Obviously, some wireless and some wired. I don't have access to all of them, some are my sons', but I try to make it count!!! (no pun)
