Even before I knew about the wonderful DSLreports bufferbloat test, I had
started working on a document to help people like that (e.g. Ookla)
understand how to do bufferbloat testing.  The document also grew a bit
beyond that topic, by the time it was done....

The document is at:

https://docs.google.com/document/d/1z5NN4WRKQKK-RtxtKR__XIwkybvsKEmunek2Ezdw_90/edit?usp=sharing

Comments welcome.

It's intended long term home is the bufferbloat.net wiki, but I've found
Google doc's commenting feature really useful.
