Arm Speed
The maximum speed, in the direction of home plate, that the wrist is traveling. Measured in meters per second (m/s)
Arm Slot
Angle of the forearm relative to the ground between maximum external rotation (MER) and ball release (BR). Which can be a powerful player comparison metric, delivered in degrees.
Knee Extension Velo
The angular velocity of the front knee straightening after foot plant, which provides indicators of velocity potential. Measured in degrees per second.
Deception
The amount of time that the ball is visible to the hitter, after the instant of front foot strike. Measures in milliseconds.
Hip-Shoulder Separation
The difference in angle of between the hips and shoulders, occurring close to the foot plant. Measured in degrees.
