This issue was identified in this forum post: https://discuss.elastic.co/t/high-approximation-error-rate-of-cardinality-aggregation-for-low-cardinality-sets/49574

We should make it clearer in the documentation that the benchmark results in the 'Counts are Apporximate' section may be different from a users results if they perform the same test since the error depends on how the values in their dataset hash (specifically how many leading zeros are on the hash values)
