The gold line is market value — an index (not €) blending rating, age and league. It climbs through the early 20s, peaks around ages 23–27 (~14), then tapers with age. At 26, Familia-Castillo sits on 13.9, at or near its peak. The blue line is Familia-Castillo's projected Rating — 47.1 today — recomputed at each age, so it follows the same rise-and-fall as a career matures and declines.
