# Pelvis Angle to Plate Coil

> Max pelvis rotation angle away from home plate.

## Technical Details

* **Variable Type:** Discrete Metric
* **Data Type:** Float
* **Units:** °
* **Column Name:** `pelvis_angle_to_plate_coil`
* **Aggregation:** mean
* **Precision:** 0
* **Measurement:** Maximum pelvis rotation (twist) angle away from home plate prior to delivery
* **Reference:** 0° = facing home plate
* **Typical Range:** 109 – 128 °
* **Optimal Direction:** Higher is better

## Description

Pelvis angle to plate coil measures the maximum pelvis rotation angle away from home plate prior to delivery, where facing home plate is 0 degrees.
This represents the coil or loading phase of the pelvis.

## Normative Ranges

Percentile distributions by competition level from the 2026 Q1 dataset; the optimal range spans the 75th–90th percentiles.
