Don't worry about a winrate yet imo, too many people wank over winrates so early on when they move up. Just focus on getting over the money hump, getting to know the regs and how to exploit them, then after maybe 40k hands of winning measly amounts and figuring out what works, then focus on your winrate.
I think I played 35k hands of 25NL which was pretty much breakeven, the next 10k was 4bb/100, the next 10k was 7bb/100, and the last 10k has been 14bb/100, so ya know, don't worry about it yet. From my experience of 25NL, your main aims should be;
- Stop thinking everyone is playing back at you. Some are, but you aren't good in 3bet pots yet, and you're crap at hand reading (this goes for all 10NL players, including me when I frist moved there), so don't worry about trying to get tricky with better players. Yet anyway.
- Don't worry about a winrate yet, focus on losing the minimum at first, and build from there.
- Don't get down hearted when you played 50k hands and haven't won any money yet, this will be the case for most people moving to a new level, you'll earn it soon enough.
- Keep watching videos and reading articles from good players, it helps a ton.
Good luck.
