Agreed.  No issue there.  But ntpd as it stands now can still misundertand
good PPS when faced with marginal NMEA and lead to bad results.

Yup.  Exactly my point.

I'm with you there, I just fail to see why turning on logging is in
conflict with that?

We'll have to agree to disagree on that one.  And we can learn from what

Fine, and if you start logging now, you'll have the data you need then.

No, I'm just do not want us to stick our heads in the sand, saying
'la-la-la' because logging is not on.

Tuning on logging is a done deal, just make it the default.

So, you got your logging on now?  Otherwise you have missed my point.
