@NoleFam its so obvious where each of the big 3 strengths lie.
While Federer and Djokovic are pretty much even on fastest surfaces, Fed is very slightly ahead. But the important stat is Fed with his devastating fh is much better than Djokovic on the slowest surfaces.
While Nadal is much worse than Fedkovic on fastest surfaces but as surfaces slow down, his win % increase dramatically where at the slowest ends, he is virtually unbeatable.
2020 was not an advantage for Djokovic to play in such conditions. Let's not forget it was in September, at the very end unlike in Summer. And then at night conditions.
