What you say here makes sense to me.  But, out of a 500 
ping sample over the course of half a day, I was getting well
below one percent loss -- six months ago.

Now, my same sample group is going for more than three percent,
with many ten percent loss routes showing.  This has changed and
has changed commensurately with the throughput problems shown
in TCP and name lookup problems via UDP.

It may not be scientific proof, but it could very well be a good
scientific indicator.  An indicator is all I really need for the
most part.
