# Max X Factor

> The instant of maximum separation between shoulders and hips before the twisting motion of the swing. This represents the peak loading phase in preparation for the swing.

## Technical Details

* **Variable Type:** Event
* **Data Type:** Integer
* **Units:** Frame number
* **Column Name:** `max_x_factor_frame`
* **Measurement:** Maximum shoulder-hip separation angle (usually negative as its backwards twisting)
* **Phase:** Loading phase before rotation

## Description

The max X factor event identifies the moment of maximum separation between the shoulders and hips, representing the maximum amount of coil before the explosive rotation begins for the swing.

## Use Cases

* Loading phase analysis
* Power generation assessment
* Swing sequence timing
* Energy transfer evaluation
