Winrate Question

I didn't see this in the FAQ and didn't find anything using the search.

What's a sustainable winrate in 7-stud? I've just started experimenting with 7 Stud Hi this week and have been running insanely good. I know the general feeling for Hold'em is that 3BB/100 is sustainable. Is stud better than this and by roughly how much?

I'm rapidly falling in love with this game and don't want to be too heartbroken when I hit my first downswing. [img]/images/graemlins/smile.gif[/img]
