If you lose all 11 bets, your loss will b 175 units. In a $10 table, the loss will be $875. Unless you have a bet selection that wins a parlay within 11 tries, your loss will be excessive. In my testing usual bet selections, DBL, ODBL, OLD, FLD etc. are losers with 11 step parlay progression.

What is the maximum bet you have made so far? I presume if you lose the three 16 unit bets, you start at 1 unit.
Thanks.

Usually the system sellers spend a lot of time in developing a system for use by themselves. Then they check the system on paper and to a limited extent in the casinos, and find that the system tanks. They try to recoup the cost, by selling the worthless system.

Perhaps, we will never see a system that is winning, for sale, since they will be using it for themselves.

Then, there are system sellers, who make money by selling systems, like Silverthorne. He sends system literature every week, for craps, baccarat, bj, roulette, etc.
