The exceptions are flat distributions of natural numbers in a range from 1 to a power of the base, right? For example: (test 1000000 (expt 5 5) 5) -> (250490 249654 249630 250226) distribution of 1000000 natural numbers in the range 1 to (expt 5 5) and base 5. 1000000/4=250000 > natural distributions are not uniform over a fixed range. > They are bell curves of one sort or another.
