Hi coach!
In our mini club we organize mini amateur tournaments every week. There are 10 players. We all play each other. There is no problem in ranking players who have different number of wins. But how to rank players with same number of wins?
How to rank players in a group tournament?
For example, in the tournament marvellous 12, why Lin Gaoyuan's result is better than Xu Xin's?
How is "Pts" calculated?
Are there many different local rules of rating in such group tournaments?
Pos | Team | Pld | W | L | GW | GL | Pts | Qualification |
---|---|---|---|---|---|---|---|---|
1 | Fan Zhendong | 11 | 11 | 0 | 33 | 11 | 22 | 2019 World Championships |
2 | Liang Jingkun | 11 | 8 | 3 | 28 | 18 | 19 | |
3 | Xue Fei | 11 | 6 | 5 | 25 | 23 | 17 | |
4 | Lin Gaoyuan | 11 | 5 | 6 | 26 | 25 | 16 | |
5 | Xu Xin | 11 | 5 | 6 | 21 | 20 | 16 | |
6 | Yu Ziyang | 11 | 5 | 6 | 20 | 23 | 16 | |
7 | Fang Bo | 11 | 5 | 6 | 21 | 24 | 16 | |
8 | Yan An | 11 | 5 | 6 | 21 | 24 | 16 | |
9 | Zhou Kai | 11 | 5 | 6 | 18 | 25 | 16 | |
10 | Wang Chuqin | 11 | 4 | 7 | 17 | 23 | 15 | |
11 | Xu Chenhao | 11 | 4 | 7 | 20 | 27 | 15 | |
12 | Zhao Zihao | 11 | 3 | 8 | 19 | 26 | 14 |

Hi Ardak,
If players are even on the number of wins then it goes to the matches played only between those players.
In this situation we would need to look at the results only between 6 players on 5 wins. Then as each player's place is determined their results are discarded and again it goes to a count back between the players that are tied. Here is the rule which will explain it a bit clearer I hope.
3.7.5.2 If two or more members of the group have gained the same number of match points their relative positions shall be determined only by the results of the matches between them, by considering successively the numbers of match points, the ratios of wins to losses first in individual matches (for a team event), games and points, as far as is necessary to resolve the order.
3.7.5.3 If at any step in the calculations the positions of one or more members of the group have been determined while the others are still equal, the results of matches in which those members took part shall be excluded from any further calculations needed to resolve the equalities in accordance with the procedure of 3.7.5.1 and 3.7.5.2.

Hi coach!
How to rank 5 players in a group if they have equal number of wins. And their win/lose ratios between only these 5 players are:
player 1: 10/8
player 2: 10/10
player 3: 9/9
player 4: 8/8
player 5: 6/8
I know that player 1 has the best result, player 5 has the worst result. How to continue ranking players 2,3 and 4?
Must we look at their win/lose ratios of only between these 3 players?
Or must we see their points in each set?

Hi,
Yes you would go to the result only between the 3 players involved. Have a look at the wording of the rules:
3.7.5.1 In a group, or "round robin", competition, all members of the group shall compete against each other and shall gain 2 match points for a win, 1 for a loss in a played match and 0 for a loss in an unplayed or unfinished match; the ranking order shall be determined primarily by the number of match points gained. If a player is defaulted after the completion of a match for any reason, he or she shall be deemed to have lost the match, which shall subsequently be recorded as a loss in an unplayed match.
3.7.5.2 If two or more members of the group have gained the same number of match points their relative positions shall be determined only by the results of the matches between them, by considering successively the numbers of match points, the ratios of wins to losses first in individual matches (for a team event), games and points, as far as is necessary to resolve the order.
3.7.5.3 If at any step in the calculations the positions of one or more members of the group have been determined while the others are still equal, the results of matches in which those members took part shall be excluded from any further calculations needed to resolve the equalities in accordance with the procedure of 3.7.5.1 and 3.7.5.2.
3.7.5.4 If it is not possible to resolve equalities by means of the procedure specified in 3.7.5.1-3 the relative positions shall be decided by lot.

Thank you coach!
Language of this rules is not easy for me. To be sure that I understand you correct, I want to show my calculations:
Then I consider only players 2,4,5.
Did I understand you correct? We don't need to look at the points of each set, am I right?
Alois Rosario from PingSkills Posted 1 week ago
Hi,
Yes your calculations look correct going just on the results between the 3 players.
Ardak . Posted 1 week ago
Initially, all of 5 players have 2 loses and 2 wins.

I hope you took into account the fact that Initially, all of 5 players have 2 loses and 2 wins.
Alois Rosario from PingSkills Posted 1 week ago
Yes initially that is how you work out the 1st and 5th place.
