I'd break it down the opposite way:

$2000/month playing regular work days (5 days a week) = $2000/22 = $90 per day.

$90/day divided by $5 per hundred hands (10bb/100 hands) = 1800 hands per day.

Each table is approximately 60 hands/hour or 30 hours total so you could play 5 tables for 6 hours, 10 tables for 3 hours, etc.

Somehow that seems ridiculously easy.

Of course you have to factor in variance which I'm sure changes things dramatically. It also means you're living on only $24k a year, which won't certainly pay my bills.

If I apply the same formula to 100NL playing say 20 tables for four hours per day = 80 table hours*60 hands per table = 4800 hands = 480BB won per day or $480 per day for a monthly income of over $10000. Now that's some cheddah.

Sorry if my post was unwarranted or wrong, I'm just a math geek.
