OK, this I find frustrating. I directly answer the opening post (the only one to do so) with an interesting scenario which is more than 10 years old and no one even acknowledges it.
They were probably distracted by your avatar and signature, I know I was. By the way, you could have fulfilled that promise by taking a photo with a rear view.
Anyway, thanks for the info. I know it happens in the WTA all the time, that someone is the #1 player without winning a slam, but I wasn't sure if it had happened in the ATP before. I know it's hard for casual tennis fans to understand the 12 month ranking system, but these are the same people who think there are only two tournaments a year (Wimbledon and the USO). The ATP has done a pretty good job of spreading out the points, but Rafa getting the clay court Masters sweep and having nothing to defend for the second half of the season is a very rare scenario. I think the rankings system will survive this anomaly.
