The downtime provided by the damage and loss application in the rWHALE v1.1 workflow should be in worker-days.
However, I suggest you migrate to a more recent version of rWHALE. We have been developing a major update over the last year that is accompanied by a desktop application and will become the supported version in the very near future. It also has more detailed documentation available that should facilitate its use. Although it has not been released yet, since its development is open-source, you can access the most recent version of the workflow applications and the documentation in Github.
The documentation is available here:
https://nheri-simcenter.github.io/RDT-Documentation/The User Manual describes the desktop application that is not yet available. The developer manual provides information about building the backend applications and has examples that can help you get started with running them.
The backend applications required to run the regional workflow are available here:
