Baron and Schneids have 7-10% higher VPIP than me. Their WTSD and W$WSF are both significantly higher. My W$SD is the same though.

Do you guys play a lot more HU and 3-4 handed? I have a hard time seeing where I'm going to add enough weaker hands to get close to that level of VPIP AND increase my WTSD%. I play almost exclusively 6-handed or 5-handed.
