Deliberately empty country

match ← All flat growth benchmarks

Bouvet Island's selected provider calendar has no columns; the saved model still retains country selection, coverage policy and the embedded snapshot.

Input

benchmark/inputs/v5/country-basic-96.json: 96 history rows and 4 forecast rows.

Output

Largest difference: 1.1e-11 (< 0.0001% of the input's range).

Every forecast row from both libraries.
