So you want the smallest and largest absolute offset. You already get
the minimum and maximum offset. So the maximum absolute offset should be
easy to spot.

Showing only the maximum absolute offset is not great. It is useful to know
if on average probes are behind or ahead of the time source. Only showing
absolute offsets doesn't show that.

Why would you want to know the smallest absolute offset?  That's just
measuring noise.
