I have been following another of my systems. This one I bet 2 horses a race to make a $50 profit, but at the moment it'd showing a loss of $39. However, I do believe it will come good soon.

I've been using this excel formula to work out my bets on each horse.

(39+50)/2.40

39 is the amt lost
50 is the target


The losses are added to the target.

any suggestions.
