.. and I have one reporting -22! Hence the need for more investigation

Here's a typical line:
56006 12567.480 0.003754344 7.420 0.000799395 0.036695 6
Precision of the fields:
second: 3 digits, milliseconds
offset: 9 digits, nanoseconds
drift compensation: 3 digits (of parts per million)
estimated error: 9 digits
stability: 6 digits
polling interval: integer

Yes, for -19, but what about my -22 system? In any case, I was simply
suggesting that the same data should be available through ntpq as through
loopstats. The precision with which that data should be reported is not
an issue in the bug report.
