Arm-slot presets set release height, side and extension, then aim at the zone center. Speed and spin stay independent. Delivery plays at 0.5×, followed by your selected flight speed. Stylized motion; the pitcher fades after release to keep the ball visible.
Dashed reference: the same release with gravity and drag, but no spin or wake forces. The gap shows aerodynamic movement. Reference controls never change the current pitch physics.
Overhead and side views reveal the full flight. Separate axis scales make small changes easier to see; distances are in feet.
