Description
Time to launch measures the duration from swing initiation to the start of pelvis velocity initiation (launch event), indicating the preparation phase before power generation begins.Normative Ranges
Percentile distributions by competition level from the 2026 Q1 dataset; the optimal range spans the 25th–75th percentiles.| Population | Optimal Range (25th–75th) | 10th | 25th | 50th | 75th | 90th |
