Original prompt · V-Index 1.8

Draft a demurrage clause for an LNG charter from Qatar to Rotterdam. Standard terms.

Audited rewrite · V-Index 9.3

Draft a demurrage clause for a Q-Flex LNG charter, FOB Ras Laffan to CIF Rotterdam-Gate, governed by English law, BIMCO LNGVOY 2024 base. Laytime 36 hrs SHINC each end, demurrage USD 145,000/day pro rata, half-rate dispatch, force-majeure carve-outs limited to government order or named-storm. Output the clause only. No preamble.

Auditor's diagnosis

Saying 'standard terms' to an LLM is the most expensive phrase in commodities trading. The model invents BIMCO numbers that look real. Naming the form (LNGVOY 2024), the law, and the rate fields collapses ambiguity — DeepSeek V3.2 actually outperforms GPT-5 here at 1/15th the cost.
