OK, first I thought it was because the number of runs was too low. This
could have been a problem because on the tail of the distributions
n_expected(bin i) a fraction when it divides the squared difference
might inflate the values.

No such luck.

A statistician friend of mine says when the number of simulation runs
is very high (>10^6), the chi square test is so sensitive that it can
be thrown off by deviations from ideality.

All of which is totally counter-intuitive to my notion that more
sampling should yield more accurate/better results.
