Formula, assumptions, and limits

\text{Net} = (\text{Used}_L + \text{Used}_D) - (\text{Allowed}_L + \text{Allowed}_D)

Symbol	Meaning	Unit
$\text{Used}_L$	Hours used at load port	h
$\text{Used}_D$	Hours used at discharge port	h
$\text{Allowed}_L$	Hours allowed at load port	h
$\text{Allowed}_D$	Hours allowed at discharge port	h
