Let's get one thing straight: you cannot tell from the naked eye how fast or slow a court is. Especially how fast or slow different hard courts are.
You all have no idea. Have you all got speed radar guns? No. So shut the flying fuck up then.
And you also can't tell how high bouncing a court is.
You think one shot bounced high, but maybe Federer put a lot of topspin on that, so it would have bounced high on any surface.
Again, fuck off.
Completely disagree. Evaluating differences between slow or fast HCs is difficult yes, but it's quite easy to get a general idea on the court speed.
