Yes, both Tobias and I misread it, but it doesn't matter, you can still 
apply the same procedures I described in my email, in the other direction.

Either build a low bandwidth simulator using dummynet:


and smokeping across it, or draw some graphs by hand in a drawing program 
like Inkscape, or just remember this:

* the lightest grey is for the most outlying packets (the fastest and the 

* the darkest grey is for the ones closest to the median

* darker layers go over lighter

* so the amount of light smoke you see is the distance between the 
outliers and the main bunch

* and the amount of dark smoke you see is the spread of the main bunch.

Cheers, Chris.
