I can't win on Friday's or Saturday's (low content)

[bball904]

Does anyone track their performance by day of the week. If so, shouldn't the weekend be more profitable? That's what logic suggests, but my results sure don't. I know it is probably mostly a sample size issue, but does anyone have any other thoughts what issues I might be having?

These are my results in $55 sng's on Party by weekday.
