Always remember that Dutch betting is a method of staking and NOT a method of selecting!! Basically what I am saying is if your selections are poor then Dutching will not save you.If you choose your races carefully( I prefer good class races with the fav at 2 or 3/1)then it is quite possible to make money by either

a) betting to win a certain amount per race

b) betting a certain amount per race,as suggested by Baghwan

The first step you MUST TAKE is to convert your selections odds to percentages.

If anyone is interested we can take this further
