Pick one doz. for every hit with that dozen place 1 split at the unhit part of that columnstreet
When 1 split is bet, double bets after 12 spins without any other hit
When 2 splits are bet, double bets after 6 spins, without any other hit
When 3 splits are bet, put the same amount as bet within the 2 unhit dozens and double once, then double bets for each loss, until hit.
