This is a 1/4 kind of bet...an experiment so far, more testing is needed...
Procedure: Begin placing 1 street within the unhit part of the Doublestreet hit, next when a new dozen hit, (same procedure)--place 1u at the unhit part of that particular DS hit. Now when 2 streets are bet within two different Doz, place 1u at the last unhit dozen. IF any repeat or zero hit before the second street is bet, double bets when the second street bet. Progression double bets for each 2 losses in a row...
Bank/stoploss: 1000u
