I agree no system is perfect. LCW is WR1 because he participates in more tournaments than many of the other top players, particularly LD, within the time period specified by BWF. And he did well in most of these, I'm sure. Most will agree that LD is the best player right now although he is ranked not WR1 but a few rungs below at WR4 or WR5 perhaps. It seems more appropriate that he should be WR1 to reflect his true standing so that he will be the top seed in the tournaments he participates and not now when he normally gets a lower seeding and has to face off LCW even before the semis. If these two are the top two best players in the world, they should be seeded 1 and 2 and placed in different halves in the draw. Then we can look forward to a more exciting finish. But how to devise a ranking system that both reflects the true ability of the player and be fair to all professionals? What is wrong with the present BWF system? What is the present system in the first place? LD does not play in all the SS tournaments and LCW is going to follow suit soon. In a relatively short time there may emerge a new World No.1 in the absence of these two top players if one or more of the other current top 10 players participate in many more tournaments than either LD or LCW. These will then distort the seedings again and the better players may be knocked out sooner than expected as LD and LCW may have to meet again in R2 or QF. Therefore what do you think the BWF should consider if they need to devise a better system for world ranking purposes? Should they: 1. Disregard the time period, or cut-off time like a player's performance only during the past 12 months or more? 2. Extend the time period to cover 2 years or longer, for example? This may neglect the player's current form! 3. Consider only the player's result in the last 5 or 10 tournamanents he participated, so that a player like LD who may not have taken part in many SS tournaments or those that carry ranking points, but did well in many of them, will still retain their accumulated high points. 4. Limit the time frame so that a player who has scored very high ranking points but who did not play in tournaments during the year for various reasons like injury, marriage, pregnancy, etc, will not continue to enjoy a high seeding? Neither do we want to see a previous champion like PG or WCH having to play in qualification matches once they have recovered from injury and are ready to compete. What other considerations do you think should be added or deleted?
