        not exactly.. the RTT depends mostly on the bandwidth between me
and the parent proxy... which is several magnitudes faster than the
bandwidth between the parent proxy and the site I want to fetch the page
from..
I want this dynamic weighting because the avg bandwidth of these parent
proxies fluctuate
