If we look at this issue from another view point ........
6年来参加全国个人赛有级人数:
2003 年 22人;
2004 年 24人;
2005 年 14人;
2006 年 22人;
2007 年 28人;
2008 年 22人。
So, the actual problem is not enough 有级 for the competitions. :(
If we study (e.g. to study those teams joined 全国团体联赛 in 2003 and / or 2004 and those teams did not join in 2003 and 2004) the issue by teams, may surface even more problems. :(
