I'm not totally convinced this is useful. The limit is about "what is
significant" and that depends on what you are trying to measure.
There's an (absolute) lower limit somewhere between 0.1 and 1.0 but I
think we can just pick a reasonable default and let people use the
command line switch if they want to override it.
