Yes, a common concern.

A few other tricks.  

Ntpd starts to use reclcoks and chimers in the same order as in the
ntp.conf file.  So put your best chimers at the top, worst chimers at
the bottom.

Add the 'refer' keyword to your PPS reclock statement.

Use a shorter poll on the more accurate sources.  They they will converge
faster, and be selected before, your other sources.
