[ntp:questions] Re: Problem with good synchronization.

The problem I observed was, when three strata bulls and a number of cows 
were involved, developed a deadly embrace where the cows saw the stratum 
oscillate first to one bull and then another. This caused frequent 
timeouts as the cows waited for a stratum lower than theirs to come 
back. The bottom line is not to be so adventurous, keep the bulls at one 
stratum and let the cows eat equal stratum grass.
