Write a prompt for plain text with lines starting \"Original plan:\", \"Delayed plan:\", \"Impact of delay:\" and \"Check:\". Each plan line shows each renewal group as monthly revenue x 10% x months remaining in FY27 (calendar year, from the effective month through December), then the total. The delay moves every effective month later by 2 months. Show the math.

Monthly revenue before the increase, by renewal month:\n- January renewals: $200,000 per month\n- April renewals: $300,000 per month\n- July renewals: $500,000 per month\n\nOriginal plan: the increase starts in each renewal month (January, April, July).\nProposed delay: the increase starts 2 months after each renewal month (March, June, September).\n\nMonths remaining counts the effective month through December. Example: an effective month of October would have 3 months remaining.\n\nNotes: churn and volume changes are not included. The CFO asked for the FY27 revenue effect of the delay before the Nov 24 pricing meeting. The figures are billed amounts for the month and match recognized revenue. A sales memo says the delay will \"cost about $100,000\"; that figure has no calculation attached.","rules":[{"type":"plainText"},{"type":"maxWords","max":130}],"promptHints":[{"label":"Names the four lines","patterns":["original plan","delayed plan","impact of delay","check"]},{"label":"Counts months","patterns":["months remaining","effective month","through december"]},{"label":"Shows the formula","patterns":["x 10%","monthly revenue"]},{"label":"Asks for a check","patterns":["check","2 months"]},{"label":"Caps length","patterns":["\\d+\\s*words","under \\d+"]}],"mistakes":[{"title":"Miscounting months","why":"The AI counts the months after the effective month or uses 12 for all.","fix":"Add: \"Months remaining counts the effective month through December: 12, 9, 6 originally; 10, 7, 4 delayed.\"","checks":["r0","r1"]},{"title":"Trusting the sales memo","why":"The AI repeats $100,000.","fix":"Add: \"Do not use the sales memo's figure.\"","checks":["r2"]},{"title":"Missing the check","why":"The AI skips the second way of computing the loss.","fix":"Add: \"Check: monthly increase of all groups x 2 months.\"","checks":["r2"]},{"title":"Markdown extras","why":"The AI adds bold labels, headings and a closing note.","fix":"Say: \"Plain text, no bold.
