Small reminder on sports betting ratings

Here are the three biggest families:

The European Coast

Also called decimal rating, it is the most widespread rating type in Europe. Less on the European continent, but it is important to know it. Europeans obviously think it is the most logical of everyone, because it is a simple gain multiplier. This rating is in the form of a decimal figure, like 0.5, or 5.25. For example, you deciof to bet on a football team whose rating is at 2.20. If you bet $ 100 on this team and win your bet, then your gain will amount to 2.20 x 100 = $ 220. Child's game, right? This rating model is so easy to understand at first glance that it is about to become the norm worldwide.

The British rating

With its small name Faction Format, the British coast is like everything at home: apart. It was in the 19th century that they set up this somewhat bizarre system. From a completely logical point of view, it remains in the line on the decimal side, the English have simply decided to Transform this system into fraction ! So the decimal rating of 0.5 gives ½ British side. For the English, it flows from source, but for Europeans (yes, because now the distinction is official!) You have to have a certain gymnastics of mental calculation, that is to say convert the fraction into decimal. Small test, a British rating in ¾ gives a European dimension of…? 0.75! Bravo for those who follow! So if you have bet $ 100 on a team with such a rating, you will earn $ 75. We agree, this example of a bet is not at all advantageous, but we had to find a simple way to explain this eccentricity to you!

The American rating

Soberly nicknamed the US format, the American side is very vague for Europeans. First of all, be aware that it is possible that the rating in America is positive, or negative. To translate into decimal language, you will have to go through a paper voucher, or a calculator for the most panicked! The formula is as follows. (100/American rating) +1. And to calculate the most interesting, that is to say how much you will win, it will be necessary to calculate this way: setting X (American rating/100) +1. We hope they are more used to it than us, because the American ratings give us cold sweats, even as professionals in the environment! To cite a concrete and demonstrative example, if you place a bet of $ 100 and the American rating is at 185, let us calculate the gain: 100 x [(185/100) +1] = 285, and 100 x (185/ 100) = 185, you will earn $ 185 on this bet. Get started, with small sums and small bets, you will be able to familiarize yourself with all these coast systems! Most operators offer a functionality that allows you to change the dimension system so that it is more readable depending on the preferences of the bettors.
