Nothing special when compared to Big3.Open Era Win percentages.....
Laver was 30 when the Open Era started. and he's still top 10 on 2 surfaces. Just from the end of his prime. Insane stuff.
2011-20 Federer would be #1 on grass, #2 on hard, #16 on clay
2016-20 Nadal would be #1 on clay, #7 on hard, #7 on grass
2017-20 Djokovic would be #1 on hard, #1 on grass, #11 on clay
