This PR contains testing for the accuracy of the HLL estimate for new clients in the activity log. In addition, it contains 2 separate bug fixes. The writeup attached will have more information on the accuracy testing, along with ideas on how to improve accuracy. However, from testing it seems like the accuracy is good enough to float up as an estimation, with the primary use-case being to identify large influxes of new clients in a set billing period.
Writeup: TBD
