I don’t have specifics for their test config, but most of the platforms would determine ‘little burden’ by looking for cross traffic (aka user demand on the connection) and if it is non-existent/low then running tests that can highly utilize the link capacity – whether for a working latency test or whatever.

I dunno – I think the research & measurement community seems to be coalescing around certain types of working latency / responsiveness measures as being pretty good & predictive of real end user application QoE.



> By all means participate if you want, but I suspect that the "raw data" will not be made available, and looking at the existing reports, it will be hard to extract meaningful comparisons relevant to real user experience at the test sites.



Not sure if the raw data will be available. Even if not, they may publish the parameters of the tests themselves.
