Federer's achievements after just 2012 US Open - If he had retired like Sampras after 2002 US Open

[McEnroeisanartist]

Federer was almost the exact same age at the 2012 US Open as Sampras was at the 2002 US Open when Sampras played his last match.

What achievements did Federer have after 2012 US Open?

Grand Slams - 3 Titles, 4 Finals, 7 Semifinals, 6 Quarterfinals (Same # of total Grand Slam semifinals and quarterfinals as Wilander)
ATP Tour Finals - 3 Finals, 4 Semifinals (one more final than Nadal's entire career)
27 titles from 49 finals
7 Masters Series titles from 17 finals
385-81 (82.62%) (Higher than all career win percentage of all players' careers except Nadal and Djokovic)

Stats makes no sense. Federer had 17 Slams at age of 31.
