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 (~4), then tapers with age. At 27, Kowalczyk sits on 3.6, at or near its peak. The blue line is Kowalczyk's projected Rating — 24.9 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.
