So where did that "down 750" that was edited in come from? Is there a session #5 -900?
As for the "wasted xx hours of my life": Been there...done that. How about "wasting" not hours, but weeks and finishing the same place you started? How about wasting 6 months (35,000 - 40,000 rounds) and being exactly where you started?

I have done the "wasted 6 month" thing, 4 different times.
But, on the flip side, how about winning 5 figures in a day (many times Ev). I had one day...one shoe actually, where I won 20 grand, which ended up being almost 1/3 of my win for a rather lack-luster year?
If you are looking for a nice smooth chart with all winning numbers close to expectation, you are playing the wrong game.
I guess what I am saying and you should have heard so many times before....short term results mean nothing (in either direction) and that's what you are presenting us with here.
