If you look at the beginning of the code, it says that both the Hardware Site Survey
and the Software equivalent take the average of 10000 (at 1/s) fixes.

This comes out to about 2h45m.  

You can then use the result of that pass as input in you ntp.oncore.0 file, so
that later startups will only take a minute or so.

[[ I in fact used the SHMEM interface and the plot programs to average for several
days, and have used those numbers for the past several years ]]
