Rep Points started being "a thing" on 1/17/10, or just under six years ago.
Couple of things happened in the past couple of months to change standings that have been in place for years.
Since I started keeping track of Rep, The Dude has been #2 in the rankings. That changed sometime between 11/2/15 and 1/4/16. Your new #2 is NUance, who has been steadily creeping up on The Dude for over a year.
