I doubt it could have completed an arc very quickly. If it swung too
early, the aggressor might be able to nip in and do some damage before
the tail was ready to be swung again.

I'd have thought they would need to be able to judge distance to some
degree, to avoid swinging too early or too late. It would seem to me
that the very end of the tail would do the most damage, since it would
be moving fastest. Why develop such a specialised and effective defense
and not hone it to a fine art?
