# Drifting Forward

> Binary indicator of excessive forward movement, determine by whether the pelvis drifts forward (towards the pitcher) more than 15 cm (~6 in) from launch to ball contact events.

## Technical Details

* **Variable Type:** Discrete Metric
* **Data Type:** Boolean
* **Units:** True/False (1/0)
* **Column Name:** `drifting_forward`
* **Aggregation:** rate
* **Precision:** 0
* **Optimal Direction:** Lower is better
* **Unknown Value:** -1
* **Threshold:** 15 cm (\~6 in) forward movement
* **Timing:** Launch to ball contact events

## Description

Drifting forward indicates excessive forward movement of the pelvis during the swing, which can compromise balance and reduce power generation efficiency.

## Use Cases

* Forward movement analysis
* Balance assessment
* Pelvis stability evaluation
* Technique correction
