From the doc:

mindist mindistance
    Specify the minimum distance used by the selection and anticlockhop
    algorithm. Larger values increase the tolerance for outliers;
    smaller values increase the selectivity. The default is .001
    s. In some cases, such as reference clocks with high jitter and
    a PPS signal, it is useful to increase the value to insure the
    intersection interval is always nonempty.

It controls flopping between chimers, but your problem is in bad
chimer selection.

I'm guessing that now you config is clean, you no longer need that.
