Do you have the complete list of those matches? I'd like to have a look. I can probably remember half of those (vs Nalbandian @ TMC 2005, vs Nadal Rome 2006, vs Nadal Wimbledon 2007 & 2008, vs Nadal Miami 2005, vs Tipsy AO 2008, vs Andreev USO 2008) if I try, but not all.hmm, i'm not sure. federer's 5 set match record is not very good (13-11 i think, especially for one of all time greats).
i'd say 5 set is only way to beat federer at slams (except on clay or when federer is subpar)
