I have recently received some reputation which made me eligible for the association reputation where you get 100 reputation for every site you have account on stackexchange. I was just looking at the top userslist here and when I scrolled to the top, I saw my username. This is for all time. Also, this does not valid as it shows me in top 2% this month.
How is it possible that I am at this top of the list? Is it because it is designed to show the user currently logged-in at the top?
