Silly stats question - includes graph

[Ojo_Rojo]

My last 74k hands, at mostly from 400NL and 600NL...





As you can see, I dont play alot, and that tends to make my downswings appear even more brutal.

During the last 20k or so hands, Ive noticed that my % of winning session stats are only 39%, could this mean I'm on tilt, playing poorly, or just running bad? Bit of all three, or nothing at all?

Thanks!!
