Data Calculation Logic

​

Past Days

• Uses original predicted cumulative target (not actual RSVPs) for the required growth line
• Actual RSVPs are tracked from EventAnalytics.rsvpHistory (primary source) or Event.attendees (fallback)
• RSVPs are grouped by day using timestamps, with guest counts included

​

Future Days

• Dynamically recalculates required growth based on actual performance
• If behind schedule: remaining days require higher daily RSVP rates
• If ahead of schedule: remaining days require lower daily RSVP rates
• Ensures the total target is still met by the event date

​

Data Sources (Priority Order)

1. EventAnalytics.rsvpHistory - Most accurate, indexed timestamps
2. Event.attendees.rsvpDate - Fallback if rsvpHistory is empty
3. Even distribution fallback - If only rsvpStats.going count is available

Notes

• Date Range: Data spans from event creation date to the day before the event start date
• Frozen Events: For past events, data is frozen at the day before the event start (RSVPs after event day don’t count)
• Dynamic Projections: Future day projections adjust based on actual RSVP performance to ensure the target is still achievable
• Guest Counts: RSVP counts include guest counts from attendee records
• Timezone Handling: Uses a 1-hour buffer for “today” to account for timezone/server clock differences
• Used in the Event Dashboard’s Overview tab to display the RSVP Growth Chart
