Improve analytic tools and provide stronger report capabilities to understand event engagement, attendance, utilizationetc

Currently the report capabilities are immature and rely on individuals to leverage excel knowledge to develop the report or the data they need. Most clubs use admin staff that do not have excel expertise.  We should have report capability within CourtReserve to be able to perform basic analytics such as: 

1. We have an event series that met 12 times. Need to obtain counts such as attendance per event, average attendance per event for the series, how many of the attendees participated for 50% of the events (6 times), how many unique members attended the series, etc.. Additionally, the admin should be able to choose what fields to include on the report display similar to the way it is structured for the detail reports. The columns in the current summary reports are not ideal.

2. Report or dashboards that allow you to understand: how did the event for the statistics above do in previous year or show a trend graph for all the years the series has been held.

3. Add additional filter capability such that within a category( i.e ideal 18 racing series), you can filter our specific event/series within that category. Exclude women's races, thursday night racing,  champ of champions so that you can get info for the remaining events in that category (Weekend racing series, Junior trophy race) .
