Hey.
You probably should expect a winrate in range of 0-0,5BB/100.
If you'll play 20% of 5/10, 30% 3/6 and 50% 2/4 for 60k hands per month, 720k hands per year my calculations says...
3-4 tables, 6,7 hours each day, 300hands per hour
~500k VPP
As a breakeven player 42,5k$.
As a 0,5BB/100 winning player 64,3k$.
And we surely don't need another grinder
