+# Wider steps (2026-10-22)
+
+Playing the progression pass, the author had a LunarLite L100 (and money for more) about
+33 minutes in, first C moon at 19 minutes: too fast. Their run's money: mostly raw sales
+from five C moons, plus one Plasma Weave sale (₥32k, of which the refining margin was only
+about ₥9k). The fix is a steeper grade ladder: each grade's price and wells, and its
+drill's yield, price and upgrade prices, scaled by the same factor (C ×2, B ×3, A ×5,
+S ×8), which keeps a moon's value (1.3–1.8× its price) and a drill's 4–5 claims per well on
+its grade, while the jump to the next grade grows faster than income. D and the PD-1 are
+unchanged. Refined items now gain about 20% over their inputs (was 40–100%).
+
+Grades: D 300, C 12k, B 90k, A 1.5M, S 24M. Drills: PD-1 1,200 (8), PX-4 8,000 (120), L100
+40,200 (900), L300 645k (20,000), LRE 9.44M (384k), EDE 17M (880k), LCE 24.8M (1.6M).
+Sim, first moon of each grade: copies C 12m, B 30m, A 58m, S 2h33; boosts C 10m, B 21m,
+A 40m, S 1h49 (was C 7m, B 15m, A 32m, S 1h04). A real player ran about 2.5× slower than
+the sim's (C at 19m against the sim's 7m), so expect roughly C 30m, B 1h15 in play.
