the system record is a progression you keep on doubling your $ on the plays up to four games then it is considered a loss , if you win start over again betting 1 unit. So 1 unit, lost now play 2 units, lost, now play 4 units, lost now risk 8 units, and pray you win then go back to 1 unit no matter if that last play wins or is a lost. the overall record is straight up wins and losses. I hope that helps.
