Hi Dave.

You statement is correct for the complete variety of platforms ntp
supports.
However, on a Linux system (with at least 1us time resolution) you can
get reasonable estimates for the drift much faster.
Have a look at my script in
https://ntp.isc.org/bugs/show_bug.cgi?id=742
Changing the stepout as you proposed should give the same results (on
Linux).
Unfortunately, I didn't understand the meaning of 'stepout' from the
documentation. ;-(
