Description
Time to release measures the total duration of the pitching motion from initiation to ball release, indicating the overall timing of the pitch from first movement to release.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 |
|---|---|---|---|---|---|---|
| Youth | 1.07 – 1.33 s | 1.00 | 1.07 | 1.21 | 1.33 | 1.46 |
| High School | 1.20 – 1.39 s | 1.12 | 1.20 | 1.28 | 1.39 | 1.53 |
| College | 1.11 – 1.31 s | 1.07 | 1.11 | 1.23 | 1.31 | 1.40 |
| Professional | 0.97 – 1.30 s | 0.55 | 0.97 | 1.18 | 1.30 | 1.43 |
| Broad (All Levels) | 1.12 – 1.35 s | 1.02 | 1.12 | 1.24 | 1.35 | 1.48 |
