Just a follow-up. Two days later I still have the same number of
calibration errors - 25, so it would not surprise me of most of these
happened at or soon after the initial startup of NTP (which may also have
been a warm reboot).

Providing the number doesn't increase rapidly, I see no need to worry
about it. I expect there might be a few more per day at most.
