This is like saying 1 + 1 = 2, but may also equal 1 in certain cases.
Oh come on, we all know these two things are entirely different. Rafa won't be scraping in enough points at all those hardcourt masters to be #1. But he can certainly dominate the slams again. What if he stands with 3/4 slams in his hands, but Nole has a couple of tournaments like toronto and paris to his name? He'd be a computer #1 just like Federer was this year
