The Ladder System always goes up or down by ones and never repeats at any level. You wouldn't wanna stand on any rung of a ladder for long periods unless you were compelled to do so because of a certain job or chore you were doing at a certain level.
But since the basic purpose of the ladder is to go up or down, I use the Theory to keep your bets moving up or down. You go "up" the ladder as you win, you go "down" the ladder as you lose.
Your bets are all tied into Series and there will be many, many Series at each session. Naturally the obligatory Naked Pulls and Loss Limits apply and I repeat that "Broken Record" message to make sure you never forget it!
