Without separate starting records, the first deviation may be assigned to the wrong stage.
Separate three starting states. Track product, container interior and coolant in distinct fields.
Preloading check. When comparing a prepared container with one from ambient storage, record time and waiting location too.
Event record
- Container interior start
- Product start
- Plate state
- Preloading wait
If deviation starts before loading, review preparation before assuming a route cause.
