How to read it. Green = within range · Amber = monitor · Red = a clear training focus. Leg power & spring are performance markers (velocity, first-step); leg symmetry, landing load & the throwing-arm ER:IR are durability markers — training targets worth correcting and tracking over time, not injury predictions (the asymmetry-injury evidence is mixed and the thresholds are working conventions). These complement — don't replace — the biggest arm-health levers: sensible pitch counts, avoiding fatigued throwing, and rest from year-round play. · Holistic Baseball × Catalyst Performance.
