its not crazy at all. there is a sophisticated "smoothed RTT
(Round Trip Time)" algorithm running in TCP for its destinations. success
of this algo relies in the number of samples it works on. with echo
port(7) resonators have little freedom to take as many samples as they
want. of cource your bandwidth and TCBs are used for the EXPERIMENT each
time ;-)
where as dns port(53) samples reflect that server's load as well, in
which resonators may not be really interested in.
