Parachuting is when a bet may start out as a single number or street, but instead of adding units on top of the number, the bettor expands the bet to a wider area, like a dozen or high/low. Is that a progression?
Yes I think so, it is a progression, because we have to use progression.
Parachute examples:
Start and track the streets, and the Ec s, than bet :
if lose if win
1. 1unit on one EC, but wait RBR bet R, or BRB bet B -1 +1
2. 1 unit on the penultimate dozen -2 +1
3. 1unit on the last 8 streets -10 +2
4. 6 units on the last 10 streets -70 +2
Can be maybe safer if before steep 3 wait a virtual W then bet on the last
8 streets, and before steep 4 wait a virtual w then bet the last 10 streets.
...
Or
1. 1 unit on one EC, but wait RBR bet R, or BRB bet B -1 +1
2. 0,50 x 8 last streets -5 +1
3. 2 x 10 last streets -35 +1
Again wait a virtual w before step 2 and step 3
...
another ideas (streets), wait until hit 6 different streets without any repeat and
bet the last 6 ,then the last 8 ,.....last 10 streets.
1. 0,20 x 6 streets -1,20 +1,2
2. 0,70 x 8 str -6,8 +1,6
3. 4 x 10 str -46,8 +1,2
Or
1. 0,20 x 6 -1,2 +1,2
2. 0,50 x 7 -4,7 +1,3
3. 1,50 x 8 -16,7 +1,3
4. 6 x 9 -70,7 +1,3
just ideas.......
