So in the first 7 hand sequence you have a 5 net L (6L-1W) @ 1 unit bets = 5 unit Loss.
The next 7 hand sequence goes to 6 units per hand ? and with 3 net L (5L-2W) = 18 unit loss?
Then the bets go to 24 units per hand for the next 7 hand sequence ?
Basically you flat bet 7 hands cycles, as long as you get a profit the betting unit remains 1.
Whether after flat betting 7 hands at the end you are behind of 1, 3, 5 or 7 units, you increase the bet on the next 7-hand cycle by adding 1 unit to the previous deficit until you recover everything (so you stop to bet the entire cycle then restarting to bet 1 unit 7 times.
In the example, after the first cycle you are losing 5 bets, so on the next cycle you'll bet 6 units each hand until you recover the previous deficit.
Unluckily we got more losses than wins (5L and 2W) totalling 3 x 6 unit = 18 unit loss, so next bet will be (5 + 18 + 1 = 24 betting unit). Yes, we'll stay at this 24 unit level until we'll be ahead of just one hand capable to recover all the losses accumulated at every previous cycles.
And so on.
The beauty of this system is that you can win even at a percentage of losing cycles adding to your 50% a 22.66%.
In fact losing sequences as WLLLLLL or WLWLLLL or LLWWWLL and some others become winning sequences.
In the example we played 14 hands, getting 3 W and 11 L, not an awesome flat betting strategy (lol) but we know it could happen.
Let's imagine a very bad scenario.
First cycle (1 unit) = 7 L 0 W unit loss: 7; next bet 8 unit (7 + 1)
Second cycle (8 unit) = 6 L 1 W unit loss: 40; next bet 49 (8 + 40 + 1)
Third cycle (49 unit) = 6 L 1 W unit loss: 245; next bet 294 (8 + 40 + 245 + 1)
After having played 21 hands, we got 19 L and just 2 W (I discarded the lucky scenario where second and third cycles may get a W as first hand totally erasing the deficit). Our unit increased almost 300 times...
A 4.12 sigma is quite uncommon to cross but it may happen. Not mentioning that half bets are made on B side, thus we need to increase the bets by adding some units to cover the vig.
To reduce the progressive betting impact, we might start the real betting after any losing cycle or even after two consecutive losing cycles, for example.
It's quite interesting to notice that 3 players betting simultaneously the three derived roads in selective situations can't reach huge negative deviations as the possible deficit is spread between them.
Situations where all three roads provide simultaneously many univocal lines (yet assuming them as negative) are very rare, if not anybody would be millionaire very fast.
