Couldn’t the number of flows contributing to the saturation affect the results 
though, so that it would have to be specified?

I think this gets to the crux of the original thinking behind the RRUL 
specification. The RRUL “Score” section contains a lot of detail for an 
“optimum result”, and further admissions that it isn’t easy to assess:

If we could come up with one all-encompassing and reliable metric for measuring 
the “goodness” of queueing behavior, it would also make testing much easier. I 
really wish for such a test, and sometimes try to figure out how it would look, 
but I don’t think it’s an easy problem to solve.
