Diagnosis

Signal	Cause	Fix	Confidence
Stuff-to-Whiff Gap (Command)0.17	Elite stuff tunnels well but pitches land in hittable zones	Reduce heart-of-zone pitches; increase edge and chase attemptsBetter location could push whiff rate toward 24%+	MEDIUM
Arsenal Shape: Gloveside Sweep0.70	Existing Slider is present, but its movement shape does not currently cover the desired gloveside-sweep window.	Reshape existing Slider to add gloveside sweep rather than developing a new pitch from scratch.Shape refinement would improve platoon coverage while preserving the existing usage signal.	HIGH
Arsenal Shape: Gloveside Drop0.60	Existing Knuckle Curve is present, but its movement shape does not currently cover the desired gloveside-drop window.	Reshape existing Knuckle Curve to add gloveside drop rather than developing a new pitch from scratch.Shape refinement would improve platoon coverage while preserving the existing usage signal.	HIGH
