The delay column shows the same small delay on all 3 boxes.  That pretty much 
rules out something strange on the network side.

I would add a few outside clocks.  That might help you figure out which clock 
is right/wrong.  (Both Arbiter's could be setup with the same error.)

You might check the antenna cable delays.  (on all 3 boxes)  Somebody might 
have typed in the wrong number, ms vs ns or km vs feet.

What sort of setup is LeoNTP?  Is it triggering on the trailing edge of a 10 
ms wide PPS pulse?

These are my opinions.  I hate spam.
