There are advocates of that exact method on this and other boards -
” Two hits and regress/down with your bets ” -
Their premise is the majority of shooters do not get past 4 rolls of the dice -
If you ” need ” action on every shooter - you get ” action ” with this style of betting - but , early 7 outs will definitely bite you -
How many of those can your bankroll handle ? -
I wait for a shooter to throw a ” repeating box number ” before I wager on him/her -
Nothing is gauranteed that the shooter will not 7-out right away - but at least the shooter has demonstrated either a little control or luck over the dice at this time !
