Technical Details
- Variable Type: Discrete Metric
- Data Type: Float
- Units: raw: m, display: in
- Column Name:
drifting_forward_magnitude - Aggregation: mean
- Precision: 1
- Measurement: Forward distance from launch to ball contact
- Related Flag: Drifting Forward movement flag
- Optimal Direction: Middle — moderate forward movement is biomechanically normal; too little or too much is suboptimal
Description
Drifting forward magnitude quantifies the actual distance the pelvis moves forward during the swing, providing a continuous measure of the excessive forward movement identified by the Drifting Forward flag.Normative Ranges
Percentile distributions by competition level from the 2026 Q1 dataset; the optimal range spans the 25th–75th percentiles.Use Cases
- Forward movement quantification
- Balance analysis
- Movement efficiency assessment
- Technique correction
