By how much do you change the offset? And if you don't mind me asking,
why do you change it?

That indicates the offset between the NTP source and PPS source is too
large.

selectdata is only in chrony-4.0.

Yes, local should be avoided. It could be useful if you didn't have an
NTP source and wanted to trust the local clock to be close to the true
time. But that doesn't seem to be the case here.
