What is the difference between real speed and the impression of speed? If it feels fast, is it not fast? Automated website speed tests aren't a good measurement the way you're using them. They're good for a site developer to find bottlenecks but can't tell you much else one way or the other. Perhaps most of the page load time is spent loading images below the fold. You're much better just loading the page by hand and seeing how fast the content shows up. And when you do that, the impression of speed is important.
