As compared to 2006 9-round system, this year, during the arbiter course, we noticed that SIXGA has considered 3 other alternatives before the selection of 2-round knock out system for the top 4. The other two alternatives were 3-round knock out system for the top 8 (in this case, no incentive for the remaining 32 players to continue with the last 3 rounds) and 2-round knock out system for the top 4 with 2 losers from 1st round (Round 8, this year) returning to play with the main body in the last round (Round 9 this year, a bit unfair for the two losers).
As for the actual situation this year (40 players), after 4 rounds, only one with full 4 points, i.e. (add 50%) minimum of 6 rounds is enough for this year.
As there are so many (6) of 5 points, mainly due to unexpected none with 5.5 points.
In all, this year 9-round method is still a better system, my personal view only.
