Hi Wismip,
I have always been interested in the concept of Dutch betting & feel the most profitable way to approach it is to target races with 9-12 runners only & target 2 horses a race only, with a fixed amount being bet each race e.g. say $50 a race, the amount on each horse would be staggered depending on the price of the horse e.g. $34 on a 2/1 shot & $17 on a 5/1 shot.

This way , one has a chance to recover some losses more quickly if one has a good run & one is minimising the frustration of odds on value ,which often comes about when one is taking 3-4 horses a race.

Cheers.
