It his extremely questionable to assign a quantitative meaning to one or
more of the flow- and congestion control variables in TCP.

The whole VJCC kludge is a qualitative one, not a quantitative one.
Although it is implemented with quantities, these are rules oft thumb.

In addition, I don't see a "fitness of a protocol", I don't see even a
protocol here. I see a numeric gimmick with no practical relevance.
