Haha...I have quite a bit of VHS recordings of full matches all the way down to early eighties. I stopped recording them in 2009. Youtube is much easier to get quick looks that mounting my VHSI can't judge consistency from the youtube highlights. Perhaps you have a link to the whole match? I have the whole Fognini match fresh in the memory. Nadal hit so many attackable balls in 2006 and so many of his shots lost almost all their pace by the time they reached the opponent. His hitting on HC just wasn't that good, but he moved like lightning and mentally he was on his game in 2006.
It's bothersome to me that there are so many instances of his meagre hitting in those highlights considering that highlights typically show best play... He got away with it somewhat back then but still got destroyed frequently on HC anyway. Obviously, 2015 Nadal is a far cry from 2013 Nadal on HC, as that's when he produced his best stretch of form on HC.
In terms of results, 2006 and 2015 are quite similar on HC up to this point with one key difference, which is that Nadal roasted Federer in the 2006 Dubai final by this stage.

Your point is that you see no difference?
