Djokovic also now has more seasons in which he has won multiple grand slam titles than Federer or Nadal.
Djokovic - 7 (2011, 2015, 2016, 2018, 2019, 2021 and 2023)
Federer - 6 (2004, 2005, 2006, 2007, 2009 and 2017)
Nadal - 6 (2008, 2010, 2013, 2017, 2019 and 2022)
He's had 2 seasons in which he won multiple grand slam titles (and multiple masters series events), but didn't finish as the year end no. 1, which was unlucky, although given that he also has that record it's not a big deal.
I did think at the time that his ban from entering the US and playing in Indian Wells and Miami in March / April, would benefit him and his grand slam title prospects. He clearly wanted to play at those events, and Indian Wells in-particular is a real favourite for many players on both the men's and women's side. But ultimately at this stage of his career when he's in his mid 30s and chasing slam titles, there was no real benefit for him to play at those tournaments which 'lead to nothing'. He had played a lot of matches near the end of 2022 before fighting incredibly hard to win the title at Adelaide at the start of this year, so the break clearly did him good.
As long as he gets a moderate amount of matches under his belt in-between slams, that's more than good enough.
