I can only point you to the ones made by folks like the internet weather
report folks (various firms), whom neither of us would call "scientific". I
could take a bunch of traceroutes and perform a bunch of file transfers to
measure delay between various points that I notice, and post the data file.
I don't know what it would prove, specifically, about where the delay and
loss would be, as they would not be scientific (which is to say "an
experiment run in both a test environment and on a controlled environment,
to prove or disprove a hypothesis").
However, I will suggest that you take a walk through town and tell people
that your favorite ISP implements copious bandwidth throughout and to other
major service providers - something which, for the record and the benefit
of the audience listening, happens to be true. Then go on to say that you
therefore believe that the internet imposes no delay other than propagation
delay, no measurable jitter, and no measurable loss.
As you have been known to tell me, your marketplace begs to differ.
If you're not willing to make that assertion, then we have something to
