Briefing regulators: density versus completeness

Dense does not mean loud. Start with the question the agency asked in the consultation, then answer it in the first paragraph. Secondary paragraphs carry caveats, data limits, and comparator jurisdictions — each with a citation a reader can verify. Avoid decorative history unless it changes the forecast. Regulators read many responses; respect their time with headings that match their outline. If you disagree with a premise, say so early and propose an alternative framing. Late surprises read like advocacy tricks, even when your economics is sound.
