I do keep seeing people say weeks at no.1 isn’t that crazy a stat to show dominance.

What’s the general thought about it here on r/tennis ?

For context; Djokovic is guaranteed to have 409 weeks at no.1 which is just 9 weeks short to having 2x of Nadal’s weeks at no.1.

For people who say weeks at no.1 doesn’t show the full picture, how is this not a dominant stat to have ?
