At 21 the trajectory points up — potential sits near its ceiling (97/100) and market value should climb as minutes and output follow. With this floor already at 21, the ceiling gets tested by a step up in level — one to track.

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 23–27 (~23), then tapers with age. At 21, Castledine sits on 9.9, still climbing toward its peak. The blue line is Castledine's projected Rating — 49.3 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.
