  "question": "How much does the pooled reply rate change when one programme is omitted?",
  "method": "Within each stated cohort, remove all campaigns from one programme, recompute 100 * summed unique replies / summed contacted leads for the remaining programmes, repeat for all seven programmes, then report the minimum and maximum.",
  "definitions": {
    "programme": "A client or internal programme grouping; five client and two internal programmes in the source book.",
    "reply": "Campaign-level unique replies, including automatic replies; not positive replies or qualified outcomes.",
    "population": "Cumulative counters at the August 12, 2026 snapshot, not a fixed monthly exposure window.",
    "range": "A descriptive sensitivity range, not a confidence interval, a forecast or a benchmark for the US market."
  },
  "limitations": [
    "Seven programmes from one operator; neither independent campaigns nor a representative market sample.",
    "Offers, audiences, duration, repeated contacts and internal/client purpose differ.",
    "Country, verified meetings, opportunities and revenue are unavailable in the retained campaign counters.",
    "Raw campaign and customer identifiers are not distributed."
