Federer going 16-1 in TBs in SF/F of Wimbledon (sure some were against weaker opponents, but against the 4 best opponents he faced in all those years, 07 Ned, 08 Ned, 09 Roddick, 04 Roddick he went 7-0 in tiebreaks) or having better numbers against the top 10 in 2004 vs the field, or Pete's serve numbers in Wimbledon finals vs the rest of the field is going above and beyond against the best players though. Djokovic certainly didn't have a habit of raising his game like this, Ned on clay beat up on so much hapless cannon fodder I doubt it's the case for him either. However I think Nadal's numbers on break points are quite good though, and by the eye test he raises his aggression down BPs, at least the good versions of Nadal.
