Why can't I win on weekends?

I've been playing the $10+1 at Party for the last month and a half. I'm yet to show a profit on a weekend. They've been absolutely terrible to me.

I have a 3% ROI on weekdays (which is far from good, I know), and my ROI on weekends is -17%. There's obviously something in my play that is producing this, I just can't put my finger on it. I went through HH after HH and I just don't see any differences in my play.

There's obviously a lot more fish on weekends, so that should account for an increased variance, but not as much as to have such an impact on my results.

What do you think I should look for in my play to find the reason for such results?
