The reason for test data is that you can't tell the true speed of a connection to the internet by just looking at the connection from the computer to the first network appliance.

E.g. if you know that everty evening you're at home - then upload all done results and download new jobs for ~1 day. But if your laptop stays at one place for days then you'll probably know which network connections is better. I do not understand the reasons why we need to upload/download trash data just for testing every time.
