How much does the World Cup score affect the ranking of national teams?

When calculating the score of each game, FIFA first looks at the rankings of the two opposing teams. If the lower ranked team wins the top ranked team, the accumulated points will be higher than the lower ranked team, and the lower ranked team will have higher points. Even if the lower ranked team loses to the top ranked team, it will get points. The purpose of formulating this principle is to encourage weak teams to compete with strong teams. After that, we have to consider the situation of scoring goals and conceding goals. The more goals you score, the more points you get, but never more than when you win. The more goals conceded, the more points will be deducted. Then add the score of the winning relationship with the score of the winning goal, which is the basic score of the game. If it is negative, it will be calculated as 0. Just like China lost to Haiti on August 3 1, although we scored three goals, we lost four goals and lost the game, so the cumulative score can only be zero. After that, we should also consider the situation of home and away games, and the team that fought away from home scored 3 points. For example, the matches between China and Haiti and Costa Rica were played in a neutral way, and neither side scored extra points.

After the cumulative score is calculated, FIFA will also consider the nature of the game. For example, the matches between China and Haiti and Costa Rica are all friendly matches. According to the regulations of FIFA, the matching coefficient of friendly matches is 1.00. So the cumulative integral should be multiplied by1.00; In the case of Asian Cup qualifiers, the coefficient is 1.50, and the accumulated points are multiplied by 1.50. In this regard, China, as the host of the Asian Cup, can only participate in friendly matches and cannot participate in the Asian Cup qualifiers, and China has suffered some losses.

After considering the natural coefficient of the game, the score should also consider the opponent's region. According to the level of football on all continents, FIFA has also formulated corresponding coefficients. For example, the current coefficient in Asia is only 0.95, that in Central and North America is only 0.95, and that in Europe and South America is 1.00. For example, China drew with Brazil in February this year and with Chile in August, and the score after the game was multiplied by1.00; After losing to Costa Rica, you can get 4 to 5 points, but because Costa Rica is in Central and North America, you have to multiply it by 0.95 to get the final score of a game.

However, in order to reflect the level of each team more truly, FIFA not only considers the results of the last 12 months, but also considers the results of the past seven years when calculating the rankings of each team. For example, the ranking in August 2003 actually calculated the score of a team's game from September 2002 to August 2003, accounting for 8/8; From September 5438+0 in 2006 to August 2002,1February accounted for 7/8; From September 2000 to August 2006, the scores of 5438+0,1February accounted for 6/8; And so on. All the annual points are added up to get the final monthly points of each team announced by FIFA. This is why China didn't play any international competitions from March to July this year, but its score dropped from 530 in March to 505 in July. China didn't play games, so his score won't improve. However, in previous years, the number of games in China was different every month, and the score was also different. After the cumulative addition, the score will naturally decline, and the degree of decline will be different every month.
