I'm not seeing similar results.  Using ntpq I see a fixed .004 jitter
however I'm not sure that's the right metric.  I should think clock jitter
from loopstats would be more apropos.

I'll collect some more data.

I'm using the rpi pps kernel that's floating around with Debian 7.6. It's
driven by a "Sure" board with an MTK GPS.
