World Mixed Team Ranking
IBF World Ranking
[May. 3 2007]
Do you know how BWF computes this? What's the formula?
looking at the chart, they choose the best ranked palyer point into each category. So, the formula is 1+1=2.
It is computed by cxytdn himself. By simulating each tie where the higher-ranked player wins, he forms a completed league table. Each win gives 2 points. China beats everyone else and therefore has 85x2 points.
Ranking for Mixed Team
This ranking is based on the Ranking points of the highest ranked player (or pair) of five individual events of each Association, ranked on the current individual World Ranking lists. Even if an Association has only one player (or pair) ranked on the individual World Ranking list, the team of that Association is still ranked. Players non eligible to represent their Association are not taken into consideration.
To set up the team ranking list, each team is opposed to all the other teams in a computer simulation (round-robin), in men's and wommen's singles matches and men's, women's and mixed doubles matches using the Sudirman Cup system. 2 points are awarded to the winning team of each of these matches, the losing team getting 0 points. When there is a tie, which may happen when players of opposing teams have the same Ranking, each of these teams receives 1 point. The final ranking order is determined by the total number of points earned by each of the teams.
A virtual match won would give the team 2 points, a tie would give 1 point and a loss does not earn the team any points. The total number of points gained by a team determines their Team Ranking.
These team ranking lists are taken into consideration for seedings at World Mixed Team Championships.
In your ranking, Malaysia is ranked second. You probably use number of matches won and lost. In the BWF seeding, Malaysia is seeded fourth. Although it made no difference in the end, I wonder how they come about the seeding.
I think the 4th place for MAS is better than the 2nd one. You see, if MAS is the 2nd on the ranking, MAS must be in the Group where China is not, then MAS will have a chance meetting China in SF. So......
prolly another idea is to use the head to head record to determine who's ranked higher when there's a tie in points.
Further to hcyong's comments, I wonder if past mixed team records come into play. Based on the table, Malaysia are 2nd, but seeded 4th.
Could it be due to Malaysia just having been promoted and has no past record in Group 1 competitions?
this ranking is for 3 may... i thinks the fourth seed for malaysia base on after singapore open..
