D'Alembert Staking Plan - Back and Lay

WARNING, the D'Alambert staking plan could require infinite stakes, so limits need to be set other wise this could see you blow the bank pretty quickly.
 
The D'Alembert staking plan is sometimes known as the pyramid system and was devised by the French mathematician Jean Le Rond D' Alembert (born 1717) and so took his name D' Alembert for obvious reasons.
 
 
 
The D'Alembert Law of Equilibrium theory, supposes a balance of successes and failures over a long series of specific events, like horse racing or casino games.
 
The plan requires you to increase your stake by one unit after a loss and decrease your stake by one unit after a win.
 
The intention of the staking plan is to end up at the beginning of the sequence but each time making at least one unit profit.
 
In an attempt to simplify the D'Alembert process the following example assumes level stakes and level odds:
 
·On the first bet you play £10 win, bet £10 - if you lose, bet £20
 
·if you win at £20, next bet £10 - if you lose, bet £30
 
·if you win at £30, next bet £20 – if you lose, bet £40
 
·if you win at £40, next bet £30 - if you lose, bet £50
 
·if you win at £50, next bet £40 - if you lose, bet £60
 
·if you win at £60, next bet £50 - if you lose, bet £70 and so on
 
A typical D'Alembert staking sequence could be as below:
 
·bet 1 unit and you lose -1 unit
 
·bet 2 units and you lose -2 units
 
·bet 3 units and you win +3 units
 
·bet 2 units and you win +2 units
 
·sum total of units + 2 units
