Hi


I'm using ntp-4.2.8p1-beta1 NetBSD/6.1_STABLE

Ntpd needs to be in sync for quite some time before the
driftfile is created/populated. 

What ntpd related lines do you have in /etc/rc.conf

I have:
| ntpdate=YES ntpdate_flags="-4 -b -s"
| ntpd=YES
| ntpd_flags="-g -N -p /var/run/ntpd.pid"

Note:
(1) you should not have same ntpd options in both rc.conf and
ntp.conf otherwise ntpd might not start. 

(2) ntpdate is now deprecated but I find with above that ntpd
syncs within 5 to 15 minutes which nearly always results in 
no reduction in my pool score after reboots or ntpd restarts,
ie scores stay at 20.
