Just an idea, (this is not new)... it's a 50/50 bet. Moneymanagement is the key.
Procedure: First dozen that hits, (that will be your playground) place one DS at the unhit part of that particular dozen AND always 1u on each of the other two unhit dozens. For each hit, the DS-bet is re-placed at the unhit part of the dozen bet..
For an example number 7 hits, (that is dozen 1, DS 7/12) now you place 1u at DS 1/6... Let's say number 4 HIT, now you re-place the bet at DS 7/12, and so on..
Progression: Double bets for each loss.
wingoal: +40u played with 1u bets, +200u played with 5u bets
Bank/stoploss: 100u played with 1u bets, 500u played with 5u bets
First tests played with 5u bets...
9/10 Games won
apx. calculation of wins/losses
losses 1*870= -870u
wins 9*200= +1800u
Total= +930u
Nice one Ignatus!
In all my years reading and studying, I have never heard the term 'martingrail' before. I like it! :thumbsup:
