What do these metrics mean?

Tunnel Score (0-100): Measures how similar a pitcher's pitches look coming out of the hand before they diverge. Higher scores indicate better deception—the ball looks the same to the batter regardless of pitch type until it's too late.

Separation Score (0-100): Measures how much the pitches diverge at the plate based on horizontal and vertical movement. Higher separation means more contrast between pitch types, making the arsenal harder to square up.

Extension Score (0-100): Measures fastball extension and perceived velocity jump. Higher scores indicate better release extension and effective speed vs release speed, making the fastball appear faster to batters.
