Mr J´s method "A complete street" has inspired me to this. If we don´t have too many chips, it might be cheaper to work on split instead of single numbers.
Mr J hopes to see a complete street (three numbers) within  the latest 12 spins.
Accordingly I hope to see a complete line (three splits) within  the latest 8 spins.
                                         1-6   = 1-4 & 2-5 & 3-6.
                                         7-12 = 7-10 & 8-11 & 9-12.
                                       13-18 = 13-16 & 14-17 & 15-18.
                                       19-24 = 19-22 & 20-23 & 21-24.
                                       25-30 = 25-28 & 26-29 & 27-30.
                                       31-36 = 31-34 & 32-35 & 33-37.
As far as I can see, it is sufficient to watch the latest SEVEN spins. When exactly two of the three splits from a line are there, I simply bet the missing one.
Without progression.
                                                  Good luck!
