I may be wrong but I believe that "synchronization distance" is the
criteria for selecting the synchronization source from the selection
set. Since synchronization distance is one half the round trip delay
plus the dispersion, it is most unlikely that servers with delays of 100
or 200 milliseconds will ever be selected unless there is nothing else
It's generally possible to find servers with delays less than twenty
milliseconds. It should almost always be possible to find servers with
delays less than 50 milliseconds.
