I cant win on Party Poker

[Beavis68]

Last year I started playing O8b on party and over about 1000 I was close to 10bb/100 (rough estimate based on hours and dollars).

Now since I got PTO, I have been tracking my play.

1300 hands and I am loosing 4.8BB/100.

I can't figure out what I am doing wrong.

I cannot win a big pot. My VPIP is about 21%

What should I look at? I am so sick of this, I play therer for reload bonsuses and barely break even.

By contrast, I am running about 7bb/100 on UB.

I know some will say small sample size, but I thought variance was lowere here.
