Dashboard

Where the saved work stands, and what needs review before it is issued. Every figure comes from a saved case.

Activity

Engineering data

The performance equations (ΔP, sand rejection, water penetration) and free-area tables the calculator uses. Edits take effect immediately for new calculations; every save is a tracked revision. Existing saved cases keep their own frozen results and are never altered.

Product

Coefficients are the fitted model parameters. A save records who changed what.
