Everything at once, minmax scaling

match ← All logistic growth benchmarks

The same combination, scaled between the lowest floor and the highest ceiling.

Input

benchmark/inputs/v2/logistic-mixed-96.json: 96 history rows and 120 forecast rows.

Output

Largest difference: 4.6e-11 (< 0.0001% of the input's range).

Every forecast row from both libraries.
