How long does Nadal keep the #1 spot? (Assuming he gets it)

If/when Nadal takes over the number 1 spot, will #1 go back and forth with Federer or someone else, or will Nadal stay on top for a few years?

This is not an argument about whether or not Nadal will take over the #1 spot. If you think he will, how long will he hold on to it?


Assuming that for some reason Fed gets injured so Nadal reaches number 1...

He will loose it quickly to Djokovic (due to hard court play)

And then Fed will return and eat them both up. :)

Can he become #1 this Wimbledon? How many matches he has to win, and how many Roger needs to lose?
