To speed up initial sync use iburst.
Your non-standard minpoll is contributing to the slow synchronisation.
However note that, in a stable environment, ntpd only requires to update
the clock parameters once every about two hours to maintain close to the
best achievable lock. The poll rate is 8 times this, so that it can
choose the "best" (lowest round trip delay) sample. On the other hand
locking in a high minpoll stops it from recovering quickly if things
As others have noted, precision time means widely differing things to
different people, ranging from the unachievable to cases where ntpd is
overkill. Many people would have a definition of precision time which
is unachievable on Windows, as Windows is not a good system for time
