BAS - correct, no guarantees.
Think of it as Akillies pointed out - just removing that one "7" every 36 rolls makes the game +EV.
Everybody eventually 7's out - just like we all gonna die.
Maybe it's just me, but how many times do you see a woman shooting for a longer period of time at a craps game than a man .... or for that matter when you go to a table and an older guy rolls longer than a young kid who is hell bent on throwing those dice as fast and as hard as possible.
If I'm playing craps I start out playing very, very low dollars until I see how that person throws. Have I been burnt before, hell yes. But has my variance gone down being up and down and all over the place since I started looking for rhythmic shooters -yes.
