if you have followed these two issues in 悟入棋途 closely, you might notice that I suggested these two changes just before the competition started but the schedule has covered 7 + 2 and only up to 7 rounds for ladies as indicated.
You may need at least 3 years or 3 times to try out a new system, as mentioned, 无三不成书.
In Bishan, we plan to use 3 years to try out 会员分级循环赛曁棋艺水平单一分级制, we are happy with the results from the last two years and all 2007 rules without change (2007 rules were amended from 2006 rules) will be used the third time in 2008/2009 会员分级循环赛 so that we are able to suggest further changes if any to 棋艺水平单一分级制 in 2009/2010.
The question should not be on why someone is not the 1st or Top 3 or Top 4 or Top 8, but more on whether we are having a better and better system, unless there are people willing to come out to help to implement the changes otherwise all will be just sitting around and the same system will be used in 2009, 2010, 2011 .......
x+1 method for Groups A & B and Round Robin for Ladies may not be the best systems due to the schedule etc, personally 分级循环赛 could be used for ladies if there are more than 10 players. If we are looking for Top 3 only, then either 分级循环赛 or 分组循环赛 is ok.
