I have been testing similar methods for so long that some parts seemed to be obvious. To me.
I´ll try to explain it better: We probably all know the six double streets:
1-6, 7-12, 13-18, 19-24, 25-30, 31-36.
In accordance with the table layout I fill in the fields as the numbers from this area turns up.
Suppose 29 comes. I´ll fill in the field in the middle column and notice that street 28-30 has come, but not the other street in that double street. So I start betting 25-27 with one unit at a time.
Similarly: If 36 comes, I add street 31-33 to betting.
When I decide to leave a wagered street it is NOT the number of hits that counts, but rather the number of fields filled in in the wagered street.
In the first part of the session I leave a wagered street right after two of its three numbers have come. Suppose I have been betting street 28-30. After starting there 29 and 30 might have come. Two of the three fields have been filled in. Then I leave that street and bet no more in area 25-30.
But I continue to fill in the fields as more numbers come (so I do not forget my deadline).
After leaving another street in exactly the same way (two out of three numbers have come)
THE END GAME STARTS.
In the end game I stay a little longer on the wagered streets: An occupied street should be full up and filled in. I leave it when all of its three numbers have come. No matter how many hits I have had there.
As stressed out my deadline is linked to exactly seven sleepers in the area. Seven missing numbers can be missing in no more than seven of the twelve streets (there is nothing like stating the obvous). So at least five streets must have been filled in at that point. But of course we might not have wagering exactly there.
