Hi,
 
We are trying to chose the 'step threshold value' for ntp daemon(ntp client)
as 32 msec instead of the default value of 128 msec and do not plan to use
-x option. This will help in minimising the number of times we adjust the
system clock (as Not using -x option will result in using slew corrections
below 32 msec offsets, hence max of 64 consecutive slew corrections and
above 32 msec offset will result in step correction) .
 
If anyone knows pluses / negatives of chosing the 'step threshold value' to
be 32 msec as mentioned above (given the need to minimise the number of
times to adjust system clock)  - please let us know. 
 
What is the probability of ntp source based UTC time straying beyond 32 msec
offsets due to network congestion, jitter - high / medium /low ? NTP
documentations available seem to suggest - ntp source based UTC time
straying beyond 128 msec is very rare.
 
Any clarifications on this  is deeply appreciated.
 
Thanks,
Ravi
