What DPI and Sensitivity do you play at?

I've recently learned that I'm a freak of nature in this regard. After asking a few pro players, they seem to play at around 400-1000 DPI and 5-10 sensitivity in game, or 8-10 inches for a 360...

I play at 2500 DPI and 20 sensitivity in game, or 1 inch for a 360. I'm wondering if I'm the only one, so what do you guys/girls play at?
