Here are the candidates:
1979 Borg:
84-6, .933 overall
17-3, .850 vs top-5
20-3, .870 vs top-10
13-1, .929 in finals
1984 McEnroe
82-3, .965 overall
15-1, .938 vs top-5
26-2, .929 vs top-10
13-1, .929 in finals
2005 Federer
81-4, .953 overall
6-2, .750 vs top-5
15-2, .882 vs top-10
11-1, .917 in finals
Note: I cannot find dominance ratios for Mac and Borg. But I found this mind-blowing with Fed:
Hard courts: Fed was 51-0 in dominance ratio
Clay courts: Fed was 15-1 in dominance ratio
Grass courts: Fed was 12-0 in dominance ratio
Carpet: Fed was 3-2 in dominance ratio. Keep in mind that Fed was on crutches 3 weeks prior to the Masters Cup, which is where all of his carpet matches were played.
