7 + 3, it is a 10-round system

7 + 2, it is a 9-round system

9 + 1, it is a 10-round system

9 + 0, it is a 9-round system

11 + 0 it is a 11-round system.

e.g. 卷心菜 joined 2009 Season 2 Group B (7 + 3) system bot not free to join +3 system at a later stage. Could we say the system is unfair to 卷心菜 as he got Position No. 2 after 7 rounds.

For 7 + 2 system, the Position No. 1 after 7 rounds can drop to Position No. 4 after +2 rounds, For 9 + 1 system, the Position No. 1 after 9 rounds can drop to Position No. 2 after +1 round, for player in Position No. 1, 9 +1 system is definitely better than 7 + 2 system. If we use Vietnam 9 + 1 system for Top 8, the Position No. 1 after 9 rounds can drop to Position No. 5 after +1 round, and for our 7 + 3 system, the Position No. 1 after 7 rounds can drop to Position No. 8 after +3 rounds, this is one of the reasons, I prefer Vietnam 9 + 1 system for Top 8 than our 7 + 3 system for Top 8.

A few writers here still do not understand what is the actual meaning of a competition system, for (9+1) system, you need to complete total of 10 rounds to qualify for the final ranking of Top 8 in 2010 Group A.

Same way of consideration, for 2010 Group B (7 + 3) system, you need to complete total of 10 rounds to qualify for the final ranking of Top 8 in 2010 Group B.

For 2010 Singapore Open regardless Group A and Group B, both are 10-round system, no one can claim he is the No. 1 after 70-meter or 90-meter in a 100-meter running event.
