How does EV work in HUSNG's? I've recently switched from playing cash and I'm not totally sure how it works with sng's.

I watched the first video of Two Men Enter on DC and got off to a bad start. I then watched the 2nd video and had a $90 day and I was shocked and thought these games were going to be easy af. I then watched the 3rd video which was about cbetting/bluffing and thats when my results went from good to bad. At around 407 games I stopped the bluffing and was only cbetting when I actually had a hand. 

Does my EV line actually represent how I've been playing and I'm just getting unlucky? I've read somewhere that it basically means I'm just getting it in good on the final hand.

And does anybody have any reccomendations on what I need to be reading/watching to beat the micro's. As far as I know, I only came across 2 or 3 regs on 888 at these stakes, the rest are usually complete fish who are just gambling.
