Market valueRating

Solid = now · dashed = projected

The gold line is market value — an index (not €) blending rating, age and league. It climbs through the early 20s, peaks around ages 22–27 (~1), then tapers with age. At 23, Courtney-Perkins sits on 0.9, at or near its peak. The blue line is Courtney-Perkins's projected Rating — 17.6 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.
