Among the wiki's faces, Jack Ma, patrick J.Adam and Sean O'Pry share the exact same value of 3.24x, while Chris Patt sits at the highest end with 4.62x and Sylvester Stallone at the lowest with 2.07x.

His Eyebrow Tilt scores 7.9 at 4.0°, and his Lateral Canthal Tilt scores 2.9 at 0.5°, both part of his full Harmony breakdown.
