@ievmartin @TennisMyLife68 @atptour @WTA @thetennisbase Tennis is still tennis, though. For correctness lawn tennis is not jeu de paume. Just like football is not an imperial Chinese sport. But even so, Novak is ahead, data is inaccurate.

@Charl1e505 @TennisMyLife68 @atptour @WTA @thetennisbase Exactly. How exactly would Tilden have 700+ weeks #1. Late 1910s, what about Johnston? 1920s? What about Cochet Lacoste and Borotra? 30s? Richards, Kozeluh and Nüslein apart, what about Cram, Perry, Crowford, Vines and Budge? Cannot possibly be counting on 40s (Kramer, Riggs).
