I believe that there is a common misconception that ntpd choses one peer 
and then uses that as the only source of time information unless and 
until it chooses a new one.

I believe there is also a related one, which does have same historical 
basis in fact, that ntpd only uses time from the lowest numbered 
stratum.  (As I understand it version three included the stratum in the 
weighting, but version 4 does not.)
