Cardinals and fill
Forecasting anchors at the decade cardinals: age 0 = a, 20 = b, 40 = c, 60 = d, with energies repeating after 80. The inner corners fill the halfway decades — 10, 30, 50, 70 — and the intermediate ages are filled by adding two neighbouring known values and reducing. The full timeline splits the ring into 56 points for per-year precision; the Matrixa calculator builds it automatically, and it agrees with the hand method at all eight anchors.
