I really dont care what google pagespeed say, it take 825 miliseconds to load, i made page for people not for robots, but i will make it to look great for google pagespeed to
First you say that "it's not a big diference, because they are very well optimized" and when I've showed the results of google page speed you say you don't care it's contradiction
Second you say " made page for people not for robots" which I agree with you but the one who bring people to your website is google so you must follow its guidelines in terms of pagespeed and contents.
Take a look at facebook or youtube with your test
And thar test is not for speed
If you have 100/100 point at the test and your site load in 6 sec because of your server
And my test have 30/100 point but my page load in 1 sec
Do you think google dosen't know that?
That is only a test for "structure" of your site, minify the css and the java script and move the javascript at the footer and you will have good result.
Have a nice day
