Where the +35 skill term comes from

Not a reputation, a measurement. We score every shot in the data ourselves and rank him among minutes-qualified peers; a fixed arithmetic turns that rank into points.

46 pts/σ × z(97.1th) = 46 × 1.89 × 0.4 (position weight) = +35

A forward-only shadow signal, as of 2026-06-02. The skill term comes from our own xG models over the open archive; the rest is earned, recorded per appearance, auditable, never back-filled. It never moves a live call.
