I've now used my version of Oscar's grind for Blackjack on 4 different trips to the casino (probably the equivalent of I'd say 30 hours of play) and each time have met my profit objective. (I bring to the table 80X my initial bet and leave when I make 40X or more of my initial bet) Yes I've gotten stopped (-40X initial bet) out on average once or twice each trip before meeting my goal but it's been a fun ride thus far. Typically (including getting stopped out), I've averaged about 8-9X my initial bet/hr. Far far better than card counting although I know you're all going to say I'm due for one or two really bad shoes that will wipe me out. To avoid this, sometimes I leave if I've just finished a sequence and the count gets pretty bad.
