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 (~1), then tapers with age. At 41, Sung-Ryong sits on 0.3, past its peak and easing. The blue line is Sung-Ryong's projected Rating — 3.5 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.
