Dutching staking plan that aims to make Target Profit on each race sharing stake over your bets. In this staking plan your cumulative liability will be different for each race, depending on selection odds, but profit will be same, no matter which bet wins.
You can tick Percentage Of Bank to set Target Profit as % of your bank.
Dutching staking plans are used when you have two or more selections per race.
Always gamble responsibly.
