When this mode fits
- The two files cover different periods.
- File B does not necessarily include all rows from file A.
- You want to analyze evolution, not only new rows.
- You want comparable metrics on a readable basis.

Warnings when periods overlap or durations differ.

Comparison exports to share the result.
