Parachute with Money Management

[watchblue]

Hi guys,
just want to ask if you have already tried some systems that can work well as parachute or plan B in case your betting is not correct.

I will try to explain better, I have recognise that very often with the electronic roulette I am able to know which one will be the next number, so for example if the last number was zero then more probably the next number will be 26 or 32 or any number ending zero (10/20/30).

Now my question is, in case I bet one dollar on each of those numbers (0 / 26 / 32 / 10 / 20 / 30) were should I add the additional 6 dollars in order to have some sort of parachute (come one of my six numbers or I go even winning the parachute bet). Let me know if I explain the strategy correctly. Also I would not like to recover in the following bets, but I am looking to recover in the same one.

Let me know if you have tried something similar.
Cheers
