Harlan,

As you know, I have no faith whatsoever in what ntpdc claims are 
performance statistics. I've been trying to deprecate that program for 
years, as it uses ancient and outdated state variables. I do stand by 
the ntpq statistics, which have been carefully updated over the years. 
Maybe somebody changed the display from dispersion to jitter, but this 
would be at best misleading.

I do see the op command using ntpq is misleading. The heading says 
dispersion but the value actually displayed is jitter. The op command 
should be deprecated, as it was added long ago with mistaken zeal. There 
might be more abuse in those commands; the only ones I watch carefully 
are the rv, as and pe commands.
