These speed tests are taken only to get an idea about the speed.
In actual practice, when you surf the speed will be very less, depending on the websites
server.
A download Manager also shows , the speed
at which the file is being downloaded.
Speed tests taken on servers at say
Delhi/Sydney/New York/ Honk Kong etc will show vast difference.
I use TweakDUN 2.2 to monitor the speed
continously.
Usually we believe to be accurate, the speeds shown from Microsoft servers.
However the link you had given, is very useful, for users with limited download ( NOT U/L). Unable to give Rep + ( 13 points ) now. . Please remind me after some time.
