I don't know if this has been discussed to death but I think that's pretty dumb actually. Why should a player lose points if he hasn't had the opportunity to defend them? Or, if a tourney was pushed up a week, why should a player get points for playing an event twice?
It has been discussed tons of times and the rankings are fine as they are. Rankings are based on the 52 week period and not based on tournaments. A player can only carried his points earned at a certain tournament for 52 weeks otherwised it will drop off. If you did'nt take them off, some players who won a tournament that was abolished the next year wont lose his ranking. AIf that happens, some players could reach 20000 points after 10 years of playing.
