Hi everybody.
I've recently completed 20k hands and I'd like to start searching for some leak.

Here's my winnings graph:

After reaching 60$ in winnings (for a bankroll of 110$) I've leveled up from NL2 to NL4. I've reached 80$ and then became to lose. So I returned to NL2.

I've noticed two things:
- My non showdown winnings line is almost horizontal
- There is a growing gap between the all-in ev line and the green line

Do I have to worry about it?

Here's my stats:

And those by position:

Any suggestion?
Thank you! :)
