I will discuss the strength of country in badminton. China ( no comment for this country. in all sector has best shuttler) South Korea ( best MD over all of the country but poor in MS. WS,WD,XD standard) Indonesia ( good MD(3 pairs in world top 10) and XD. MS and WD standard, poor WS) Denmark ( MS,MD,WS,WD,XD standard) Malaysia (MS,MD standard ( even LCW and KKK/TBH is great shuttler but malaysia doesn't have a backup). WS,WD and XD poor) Japan ( MS,WS standard. WD good. MD and XD poor) note : this analyse is based on top 6 country. so, if i say standard it means standard over the 6 top country and of course great over other 6 top country. if i say poor it can mean standard or good over other 6 top country. This analyse can be used to predict the team tournament like Thomas, Uber and Sudirman cup. Any comment and correction?
