Just to follow up here. I think what's going is that not only are the
most_common_vals being preferentially taken from the beginning of the
sample but also their frequency is being massively overestimated. All
values have a frequency of about .001 but the head of the MCV has a
frequency as high as .10 in some of my tests.
