It's a little like there's Jon Skeet, then there's nothing for a while, then there's somebody else. His average reputation increase per day is often more than 300. Of course, 200 is the typical "cap" on daily increase, but somehow he Skeets around that. He'll probably reach a million points this year.
Not that I think reputation points on Stack Overflow is very interesting or meaningful, of course. :)
(Ps, add your own id to see when you reach it: http://www.hasjonskeetreachedonemillionyet.com/155689 Mine is in quite a few years)
