# Explicit US control, multiplicative

 [← All flat growth benchmarks](/benchmarks/flat)

The same rows, occurrences, priors, mode and fitted names as the corresponding country case, but all dates are explicit events and no country snapshot is embedded.

## Input

[`benchmark/inputs/v5/country-basic-96.json`](https://github.com/jer-k/effect-prophet/blob/main/benchmark/inputs/v5/country-basic-96.json): 96 history rows and 4 forecast rows.

## Output

Largest difference: **3.5e-10** (< 0.0001% of the input's range).

Every forecast row from both libraries.

| Date | Effect Prophet | Python Prophet | Difference |
| --- | ---: | ---: | ---: |
| 2024-12-25 | 20.0010 | 20.0010 | 3.5e-10 |
| 2025-01-01 | 23.0368 | 23.0368 | 9.9e-12 |
| 2025-01-02 | 20.0010 | 20.0010 | 1.1e-11 |
| 2025-01-05 | 21.4459 | 21.4459 | 9.5e-12 |

## Timing

Median of all measured repetitions.
