Units meaning:

per_person_per_day: Group total = rate × days × persons; Per-person base = rate × days.
group_per_day: Group total = rate × days; Per-person base = (rate × days) / persons.
per_person_flat: Group total = rate × persons; Per-person base = rate.
group_flat: Group total = rate; Per-person base = rate / persons.

For Excel-like output, “Multiply by Days” applies an extra ×days to (Per-person base + Profit add) for the final “Total Per Person” column.
