Terrible Downswing...

I've stopped 9-tabling and am now 6-tabling, because I feel a little more comfortable, I'm just merging all my past results here for the data:

6th set: 4, 7, 6, 2, 5, 7, 5, 3, 3, 3, 8, 4, 4, 2, 2 = -$16.50

I think the obvious thing here is that I am just not closing well, I need to work on my end game and bubble strategy...here are the total results :-(

Games Played = 60
Amount Wagered = $390.00
Amount Won = $351.00
Net Profit = -$39.00
ROI = -10%
