I think it's the distribution of the weights what makes it unstable
and it has to stay that way long enough to reach the inf (e.g. the
exponentially decreasing dispersion in refclock after a frequency
step), otherwise it will stabilize. Absolute values of the weights
don't seem to matter.

The columns are number of the sample, weight, peer_distance.
