Since I started playing 6max ($15, $30, $60) in March 2011:
-$1592 playing 3971 games
+$800 from VIP Stellar Rewards
+$300 from Battle of the planets
+~$2,500 from Rakeback
+4.46% ROI over 1008 games at the $15
-3.29% ROI over 2012 games at the $30
-5.15% ROI over 607 games at the $60
Overall:
About +$2000 since March after 4000 games, which is disappointing for me. I feel like I beat the $30 but as you can see from the graph, I have been losing since June 2006 (See first graph)
Graph since March 2011:

I have lost my HEM database in June, so I have a graph only from June (which shows I'm running below my EV). I dont have graph since April, but my EV graph, as I remember, was about +2000 there, so combined with this graph it should mean my EV graph should reach about $0.
Graph since June 2011

My balance right now is $5K. I want to make the $30 my main game, but as I keep losing I keep losing confidence and my roll is shriking into levels I dont feel comfortable anymore. I think about moving down to the $15, where I probably have higher winrate, and thus suffer less soul crushing variance.
What is the chance I am a losing player at the $30?
