Win rate by position

[Mroberts3]

Hey all, I have about 6k hands logged in my PT database and I decided to go through and analyze some of my play and see if I could make some improvments. While I was looking through my stats I found something that struck me as odd. My position stats are as follows: (Net amount won)
Button= 101 --> following #s are # off button
1= 132
2= -3
3= 57
4= 44
5= 71
6= 10
UTG= 30
SB= -76 w/o blind=292
BB= -142 w/o blind=33

Now I know that my sample size is not very large yet, but I found it surprising that my winnings were consistant on all other positions except 2 off the button, the only place I lost money. Is this normal variance, or should I try and take a look at how I am playing in late position? Seeing my win rate at the buttion and CO, I am thinking that maybe I am playing too loose or agressive too early and maybe I should slow down when I am not on the button or CO. Does anyone else have any stats they could share that would help me out? Thanks in advance.
