Club health score

An average of three things: members kept, members who came to an event this year, and members with a working email.

The score is out of 100 and averages three parts. Members kept compares active members with active members plus anyone who lapsed in the last two years. Came to an event is the share of active members checked in at least once this year. Email on file is the share of active members renuzy can reach.

A part with nothing to measure yet, such as attendance before your first event, is left out rather than counted as zero.
