Either way, Federer has not much to defend other than the Australian Open until Madrid. That should be doable. He usually does well in Slams, so If he doesn't lose his ranking here at the Masters Cup, I don't see him losing it before Madrid. Could anyone tell me at how many weeks that would put him?
According my calculations the week before Madrid would put him at 284 weeks
