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 (~40), then tapers with age. At 23, Kabayama sits on 40.1, at or near its peak. The blue line is Kabayama's projected Rating — 52.8 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.
