VPIP Total vs VPIP by position

[TXTiger]

It seams like my VPIP total is really inflated by the sb number. My total is 18.5. But if I look at VPIP by position it starts at 8-9 and goes up to 16.5 on the button. So even on the button I am not seeing the 18.5 that my total number tells me I am.

If I go to the more detail section my Saw Flop not in a Blind number is 11.6. This seams like I am playing to tight, but I have always looked at the 18.5 total VPIP number and thought that I was doing OK.

So am I playing to tight? And does anyone have other comments on VPIP total vs. VPIP by position vs. Saw Flop not in a Blind?

My VPIP total has dropped from around 20 to 18.5, and I wonder if I am costing myself with extreme tight play.
