Proof that Djokovic has gone much further than Federer and Nadal, per slam played.
Name Match Slam M/S
Djoko 446 79 5.65
Feder 429 81 5.30
Nadal 358 68 5.26
Match = # of matches played, Slam = # of slams entered
Only four players have metric greater than 5, the Big 3 and Borg, whose metric was similar to Djoko.
Djokovic had a metric of 5.65, whereas Fedal had a metric of 5.30.
I expect the metric of Sinner-Alcaraz to be right up there with Djokovic, if not higher.
