For some reason, which I didn't discover, chrony wouldn't correct a 5-sec error for me, but that was many versions back. I must admit that I didn't find anything to configure in either chrony or ntp, using them just as they came out of the box. I still do. https://lists.debian.org/debian-user/2017/06/msg00450.html > 2.

IIRC makestep 1 3 was in chrony's default configuration. Cheers, David.
