since you bring up this matter, this is one area that the organiser(s) need to look into for solution(s) if possible.
This is also the reason for me to bring up 8 + 1 instead of 7 + 2 after 几度 asked the question of 7 + 2 or 8 + 1 for “瑞士结合淘汰一局制” but it may be too late to change since the schedule has covered 7 + 2 method.
In China, some events are using x + 1 method.
SIXGA EXCO may wish to discuss after 2008 event regarding 9 + 0 , 8 + 1 or 7 + 2 for 2009 National Open. Of course, it is almost impossible to find a perfect solution, I guess.
