How the visit time is worked out
- When the visit has no visit time of its own, its time is the Default Visit Time plus the dynamic time. Example: default 15 minutes, 2 minutes per box, a visit with 5 boxes takes 15 + 10 = 25 minutes.
- When the visit has its own visit time, that time is used and the default and dynamic times are ignored.
