Both Slam Titles and Weeks at number 1 are important markers of success. What I find interesting is that lack of relationship between them.
For instance Djokovic has more weeks at number 1 than Nadal but has 6 less slams. Or Roddick has more weeks at number 1 than Becker but has 5 less slams. Lendl and Sampras have a similar number of weeks (270 vs 286) but Lendl is behind Sampras by 6 slams.
It is my belief that there is probably more correspondence between weeks in the top 4 ie being a top contender and slam victories than weeks at number 1 and slam victories.
