I liked the question they tried to answer, if not their results. :) As I push a downstream shaper closer to 95% I have been able to get to where there is sufficient buffering one hop away to where it takes 10s of seconds or forever for an aqm to drain the result. Your efforts towards measuring smoothness seemed like a partial start to having some other trigger to get back minimum queuing, but not quite.
The fact that the 85% number is essentially folklore rather than science is bothersome. I've spent a lot of time over the last 5 years researching various models, queue theories, statistical distributions, and so on, and don't feel like I'm any further better off than I was when I started. There's always things that look promising (see, for example "hopf bifurcation" for something I'm trying to understand currently), other things like alternate statistical distribution methods, which seem to show a tantalizing hint of working, and they always peter out... There are a lot of people that believe in policers, also, and I have had such bad results with those as to give up. It would be nice to *prove* that policers didn't work or establish the bounds of their range, also. I go back and I read how clearly understood some things could be back in the 90s, and I envy those people - but I imagine those things were just as confusing at the time those papers were being written as clear as they may now seem.
