Hate to be critical, but those ranking are ridiculous. Can't argue with Ko Pin Yi at #1, but some of the players ahead of SVB don't make any sense whatsoever.
The rankings are strictly based on relatively short term tournament performance in WPA sanctioned major international events and some smaller regional ones.
You might not agree with them, but anyone ranked higher than SVB on that list has performed better in the events that are used as a whole for the last year or so.
