Yes,  that is the normal "best practice case".   But the OPand myself
some years go
both have a difference use case.     In this case no other machine
needs to know the time.
I only care about one computer.

The reason I used NTp back then and he is using it now is to calibrate
the rate of a real-time process running on that one computer.   In
this special case it makes sense to connect GPS PPS to the computer
and use no other source of time.
