If you like to dutch your bets (play multiple horses in a single race and be guaranteed a certain amount if one of those picks comes through), the dutching tool is for you. The tool allows you to play up to 12 horses in a single race To use it, simply enter the profit you'd like to earn in the race in the desired profit field or the total amount you have available to wager by changing the pull-down menu. Then place the odds of the horses you'd like to play in the various odds boxes. These odds may be in one of the following forms (3/2, 3-2, 1.5). The tool will then calculate how much you'll need to play on your horses in order to earn the desired profit. It'll also let you know how good a bet is by giving you a profit margin and a confidence number.
The profit margin simply lets you know how much of your winnings will go back into repaying your wagers and how much will be profit. The closer to 100% this number is, the better your wager.
The confidence percentage lets you know what percentage of similar bets you'll need to make in order to break even. If this number is 80%, you should be 80% sure that one of your horses is going to win. To put it another way, if the confidence percentage says, 80% you'll need to have one of your horses come in at least 80% of the time to turn a profit in the long run.
The tool will also let you know how much a specific bet is going to cost and an approximation of how much you can expect to win. Remember, it's usually a bad idea to chase a small amount of money with a large wager.
You can also choose to have the tool round off your wagers to the nearest dollar so that it displays playable amounts to wager on each horse. It's important to note as well that all wagers below $1 are rounded up to $1.00 even no matter how small they
Lastly, the confidence and profit margin numbers are still valid even if you've only entered in one horse. It's a good way to just check any wager where you know the odds and want to simply get statistics about your wager.
