Bro, stfu. You are talking about 2k hand samples, when there is like a ~20% chance you are running at 2x above EV. You just runned good in your first games. Also there are a lot of types of running bad, you can be running above EV and having an ROI that is bellow your true EV ROI.
50% is def attainable, if you are smart you wont attain it because you will change games sooner (you need to know most of the field to have that, have lots of hands on the "regs", be good with the regs dinamics etc, etc... I would turn to turbos unless you have some other reason to play non-turbos like moving to mtts latter. GL
