Designates the representation method of the ratios. It is differentiated between the European (decimal), British (break) and the American standard. In the European standard the ratio represents times the investment equals the return. If you invest 10 euros on a victory of Bavaria Munich with a ratio of 1,5, then is the return will be 15 and the clear profit would be 5 euros. In the British standard the ratio calculates the clear profit of the bet multiplied by the employment. Thus 10 become set on a victory by Bavaria Munich with a ratio of ½ then 5 euros clear profit. The American system knows positive and negative ratios. The negative ratios indicate, as the employment to be high must around 100 units win. The positive ratios indicate how high the clear profit is with a use of 100 units. In our example the ratio for the play Bavaria Munich is against Hamburg sports association -200. With the computation of the negative ratios the minus sign is omitted however. Disbursement: 10 x (1+100/ 200) = 15"
