Let's see... Found them!

score 	A+ 	D 	%
up 	9.1 	31.8 	29%
down 	163 	456.2 	36%

A+ figures were only 20-30% of the bloated D figure (:-()

I showed the article with both graphs to an outside reader and he 
spotted it instantly, and asked why I was only getting a tiny fraction 
of the "bloated" throughput.

> 	[SM] Good point... especially for upload tests, I occasionally see numbers which I know for a fact to be impossible (abovre the gross capacity of my access link) and I wonder whether all tests actually do proper reporting of the grand average capacity numbers. This should not be rocket science: take the start time of the first maesasurement flow and the end time of the last measurement flow and divide the total number of payload bytes trasferred by the total time this took.
