為什麼FIFA的排名不準
因為FIFA的計分方式不好
這次世界盃時 FIFA把美國排到第五名 把捷克排到第二名
結果美國隊 踢不進16強 捷克也一樣
美國在Elo 從來沒有進過前十名
我都看Elo的排名 http://www.eloratings.net/
Elo的排名很準
是最準的
所以中國沒那麼後面啦
中國在Elo排55名 這是他們的真正實力
中國很強的好嗎?
上次亞洲盃 中國還拿第二呢
南韓在FIFA排52 在Elo排39
當然是比較接近39 因為南韓上次世界盃可以跟排名前五的法國踢和
這裡有他們排名的記分方法
聽說是引用西洋棋世界排名系統的方法計算的
The ratings are based on the following formulas:
Rn = Ro + K × (W - We)
Rn is the new rating, Ro is the old (pre-match) rating.
K is the weight constant for the tournament played:
60 for World Cup finals;
50 for continental championship finals and major intercontinental
tournaments;
40 for World Cup and continental qualifiers and major tournaments;
30 for all other tournaments;
20 for friendly matches.
K is then adjusted for the goal difference in the game. It is increased by
half if a game is won by two goals, by 3/4 if a game is won by three goals,
and by 3/4 + (N-3)/8 if the game is won by four or more goals, where N is the
goal difference.
W is the result of the game (1 for a win, 0.5 for a draw, and 0 for a loss).
We is the expected result (win expectancy), either from the chart or the
following formula:
We = 1 / (10(-dr/400) + 1)
