In 2012, it is true that Taiwan moved its GPG but I'm not sure it 'had to'. After all, the Vietnam GP went ahead with its scheduled time 2 weeks earlier than Chinese Taipei's original time and it had a very large field. I agree with scorpion1 that it is odd that China didn't fill the ranks. I guess the combination of juniors playing junior events and veterans resting between SS and TUC affected things. Still, the Korea GPG was in just as long a run last fall and Korea alone still fielded more women's doubles pairs than the entire draw in Changzhou, and that included only one pair of juniors. It is hard to believe that China couldn't find more. Korea drew heavily from the pro club system, which contributed more pairs than did the national team. I guess they might have expected more international participation. Also, China is huge so transporting players who feel they have no chance at beating Huang/Yu or Luo/Luo across such great distances just for the sake of filling out the draw might not be such a high priority. Korea tends to treat their GPG as a modified domestic event but that is a lot easier to do when every player in the country is within a 5h bus ride. I don't agree that it is up to the BWF to prevent this sort of thing. China had a bigger and stronger field for their $50,000 International Challenge. Unless the BWF denied permission to put the GPG in February, it would seem that China might be miscalculating. I'm sure the BWF was very keen to have the former Superseries as the most lucrative stop on the newly-rebranded GPG circuit, but I seriously doubt the idea to have an International Challenge as well originated outside of China. The other question is what you would have the BWF do. If so many countries wish to hold events and can find the sponsorship money, then it seems logical to let things go ahead. I suppose to avoid the 'dilution' that RedShuttle speaks of, you could keep the number of GPGs down. Still it's hard to argue that this is a solution. The one event that shut down because of lack of sponsorship money, the London GPG, had no problem whatsoever in attracting talent last year. I haven't heard why Macau was cancelled nor why it and Korea were knocked down to GP status despite still offering (or planning to, in Macau's case) GPG-level prize money. The other solution would be to move some GPGs into the slow spots of the calendar, but for that you have to find them. It seems that players like the lulls on the either side of the TUC/Sudirman and the Worlds so it seems unwise to fill these. February is a bigger mystery. Perhaps it plays the part of a winter break that doesn't happen between SSF and Korea. The former TUC qualifiers may have played a part and certainly Europe still used February for team championships and they use the first few days of the month for nationals.
