I am syncing with three server from N.us.pool.ntp.org. I have no fudge

I am pretty sure I am just reading the man pages incorrectly, but then
others things seem confusing as well.

Uhhh, the confusing part.

I vote for higher, I have no fudge configured and my servers are
claiming to be stratum 0 when I check them from outside. But!! Never
trusting my observations until checking again, I see when I tested that
my clocks were off. So if I cannot sync, my server continues to answer
time queries but claims to be stratum 0.
I am thinking I am getting closer to grasping this.
