Live (B&M) 6/12 Lose rate

[Okee]

I made these back-of-the-napkin calculations/estimations recently, are they a reasonable estimation? Is it impossible to be profitable at 6/12 at these rates?

My local gaming establishments drop $4 / hand no matter what happens ($3 + $1 bad beat jackpot, but you only get that back if you win and should only average that in if you play an insane number of hands). Let's say I tip out an average of $2 / hand. Therefore at 35 hands / hr, $210 / hr is coming off the table. At a 10 player table that's $21 / player / hr. At the well-publicized max win rate of 1 big bet / hr a perfect player can therefore expect to lose $9 / hr playing at this game.
