# Weekly pattern, minmax scaling

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

The same weekly data with minmax scaling.

## Input

[`benchmark/inputs/v1/flat-seasonal.json`](https://github.com/jer-k/effect-prophet/blob/main/benchmark/inputs/v1/flat-seasonal.json): 96 history rows and 24 forecast rows.

## Output

Largest difference: **2.6e-12** (< 0.0001% of the input's range).

Every forecast row from both libraries.

## Timing

Median of all measured repetitions.

| Step | Effect Prophet | Python Prophet | Effect Prophet is |
| --- | ---: | ---: | --- |
| Fit | 4.35 ms | 20.7 ms | 4.8× faster |
| Predict | 298 µs | 3.13 ms | 11× faster |
| Save model to JSON | 21 µs | 437 µs | 21× faster |
| Load model from JSON | 188 µs | 2.26 ms | 12× faster |
| Load and predict in a new process | 157 ms | 1.44 s | 9.2× faster |
