Position - should this be happening?

[offTopic]

I don't have a lot of data accumulated yet, but I thought I'd ask the question anyway...over 13,000 online hands at Paradise, Party, and Pokerstars, I'm making more money (a lot more, not just a couple bucks) from the cutoff than I am from the button.

This is all from low-limit play between .5-1 and 5-10, with the majority of the hands 2-4 and 3-6.

Is this typical, or is it the sign of a leak (ie, not stealing/restealing enough) or is it just an indication of the general texture of the games?

Thoughts? Ideas?
