@@ -661,6 +661,13 @@ The *minsamples* directive sets the default minimum number of samples that
*chronyd* should keep for each source. This setting can be overridden for
individual sources in the <<server,*server*>> and <<refclock,*refclock*>>
directives. The default value is 6. The useful range is 4 to 64.
+
Forcing *chronyd* to keep more samples than it would normally keep reduces
noise in the estimated frequency and offset, but slows down the response to
changes in the frequency and offset of the clock. The offsets in the
<<chronyc.adoc#tracking,*tracking*>> and
<<chronyc.adoc#sourcestats,*sourcestats*>> reports (and the _tracking.log_ and
_statistics.log_ files) may be smaller than the actual offsets.
