How many of slam finals of Sampras`s do you think Federer would have won?

Some notes:
- Grass in the 1990s was much faster than in 2001. Stuffs like Tsonga 2011, Berdych 2010, Starkhovsky 2013, Raonic 2016 and Anderson 2018 would have been way more likely to happen.
- Federer did not do any damage at USO until USO courts were slowed down (court speed: USO 1997-2001 > USO 1978-1996 > USO 2003 onwards).
- Federer has never been a serve-and-volleyer at any point of his career. Watch his hardcourt matches in 1998-2003 and you'll see.
- Old racquet and string tech favoured serve over return.
- His FH technique, which inherited traits from both Agassi and Sampras FHs, did not exist.
- Probably Federer would have been shorter if he was born in 1971. A 6ft0 guy is not going to win multiple Wimbledons in the 1990s.

Or maybe Fed didn't do any damage at the USO early on because he hadn't fully developed by then? USO courts were quick enough in the mid to late 2000's, especially faster than afterwards.

Fed played serve and volley plenty at 2001 Wimb and significantly at 2003 Wimb. And besides grass in the 90's wasn't much faster than in 2001. 2002 is when the changes could be observed.
