Define both clocks
Synthetic click 10:00 has event matching window 10:00 inclusive to 10:05 exclusive. Local automatic inclusion also requires arrival by 10:20 inclusive. E1 event 10:04 arrives 10:19; E2 event 10:04 arrives 10:21; E3 event 10:05 arrives 10:19. Late evidence is retained for review, not erased or automatically credited.
| Event | Event/arrival time | Automatic inclusion |
|---|---|---|
| E1 | 10:04/10:19 | Yes |
| E2 | 10:04/10:21 | No:arrival late |
| E3 | 10:05/10:19 | No:event outside |
Check event and arrival separately
- Check event-time membership
- Check inclusive arrival deadline
- Include E1 automatically
- Retain E2 late review/E3 unmatched
Do not substitute arrival time for event time to make a late record fit the match window.
How many events qualify automatically?
Show the worked answer
One, E1. E2 matches occurrence time but misses arrival grace; E3 arrives in time but lies at the excluded occurrence endpoint.
Route late evidence to review
| Case | Decision or result | Reason |
|---|---|---|
| Arrival exactly 10:20 with event 10:04 | Eligible automatically | Arrival boundary inclusive |
| Event exactly 10:05 | Not eligible | Occurrence end excluded |
Keep both timestamps and the two-rule revision in the review export. The worksheet records attribution handling rather than measured campaign effectiveness.
