Can't you see that there can be 100 users on line on a upstream card and they can all be suffering extreme degradation of service. You can then have 5 users come off line (5 p2p users thrashing their connections) and the remaining 95, still doing what they were previously, then don't experience any degradation of service. To me. in my way of thinking, those 5 users were causing all of the degradation. In your way of thinking it would be that the 5 users were causing 5% of the degradation and if they came offline there would still be 95% degradation in service.

So just what are these other 95 people doing then ? None of them are downloading anything? Or uploading anything ? Or watching streaming video or listening to web radio or looking at a flash based website or playing online games or any number of other things (that actualy require data to be sent up and down) ? If they are not doing anything that requires data to be sent up and down then they are not being effected and if they are they are contributing to the congestion. When I pull off the congested motorway I stop contributing my 'one cars worth of congestion' to the problem and I in turn am not effected by the congestion. When I pull back onto the motorway I am effected by the congestion and I contribute my 'one cars worth again'.
So now you can start telling me about 1mbs users that only want to send and recieve data at 500kbs being effected by those that want to use it at full speed but the argument is the same if you think about it (along with the obvious question , why have they got the 1mbs service an not the 600kbs one). Again in analogy terms you could argue that big cars cause more congestion than small ones - and you would be right, but in turn small cars are more able to nip in and out than big cars (or use bikes if you prefer) and thus the effect of the congestion on them is proportionately less that someone in the big car.
