Ah, I didn't realize this was based on the Trimble board - I was
having a mental seizure and thinking it was using a Motorola OnCore,
as so many of the others did.  Are you really sure it is an SV6?
Trimble also made an SV8 timing that was in the same form factor  and
if it was using that it would certainly explain why you sometimes see
more than 6 satellites - although I have a vague memory that if you
talk to it as if it was a 6-channel board it starts pretending to be
one for reasons of backwards compatibility, so even if you do have the
SV8 in there it likely won't do you much good.

True, but this is time-nuts.  The pursuit of more accuracy than you
need is the whole purpose of the list :)
