Are 3/6 and 5/10 so different?

[Analyst]

Or is this just a small-sample phenomenon?

I've finished just about 10k hands at Stars, roughly half at 3/6 and half at 5/10. The results couldn't be farther apart: +5.1BB/100 at 3/6 [img]/images/graemlins/smile.gif[/img], but -1.9BB/100 at 5/10 [img]/images/graemlins/frown.gif[/img].

My VP$P is almost identical for the two games at ~25%; the only stats on the "general info" page that are very different are PF raise (8.3% at the smaller game, 9.8% at the larger) and Won $ at SD (55% and 48%, respectively). I do think that I am calling too much on the river (and perhaps the turn), but there also seem to be more "playmakers" at 5/10 to watch out for.

The game does seem somewhat more aggressive at 5/10, and the players overall somewhat stronger, but I wouldn't expect anything remotely close to a 7BB difference in win rate. Am I just running hot at the 3/6 and cold at the 5/10, or am I really that much over my head at 5/10?

I'll also go through the histories and post some example hands.
