hmmm... Well, I assumed it was a bug from a comment in analyze. >From ( near ) line 2130 in analyze.c * least 2 instances in the sample. Also, we won't suppress values * that have a frequency of at least 1/K where K is the intended * number of histogram bins; such values might otherwise cause us to * emit duplicate histogram bin boundaries. */ If this is expected, I'm also not sure what the use of maxmincount in analyze is...
