How scoring works

For a guess g and true value t (both > 0), the log-distance is d = |ln(g) − ln(t)| (the number of e-fold errors). The score is max(0, 1 − d/cap) — linear in d, hitting 0 at the question's cap and flat beyond. The cap is per-question: tighter for things an AI-aware crowd should nail (doubling times, cap ≈ 1.2–1.5), looser for genuinely fuzzy quantities (obscure dollar figures, multi-step computes, cap ≈ 5–6), set so the expected score per question is roughly constant. Non-positive, blank, or unanswered → 0.
