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 (~25), then tapers with age. At 25, Sung-Yun sits on 25, at or near its peak. The blue line is Sung-Yun's projected Rating — 36.7 today — recomputed at each age, so it follows the same rise-and-fall as a career matures and declines. Solid = up to today; dashed = projected.
