Why it is not presentable

  • Quoted a figure the analysis says not to quote
  • Made a material claim the analysis does not support

In detail

  • Slide 6 quotes 15,000: the agency's unvalidated forecast of 15,000 new TikTok customers.
  • Slide 4: “Minimal display budget retained for retargeting only.” is not supported by the analysis.
  • Slide 4: “Meta's small budget increase is to match inflation and test new audiences.” is not supported by the analysis.
  • Slide 4: “Minimal budget retained for retargeting only.” is not supported by the analysis.
  1. Slide 1 of Claude Haiku 4.5's deck
    Slide 1Acceptable The reallocation recommendation is buried in a paragraph rather than expressed in the title or a prominent takeaway.Header bar is taller and the title larger than on every other slide, so it is inconsistent with the deck
  2. Slide 2 of Claude Haiku 4.5's deck
    Slide 2Acceptable The title names the topic without stating the performance takeaway.Topic label title; no takeaway (e.g. CRM most efficient, display not working)
  3. Slide 3 of Claude Haiku 4.5's deck
    Slide 3Acceptable Long explanatory paragraphs make the supporting argument slower to scan.Small holdout table occupies only the left third, leaving the right side empty
  4. Slide 4 of Claude Haiku 4.5's deck
    Slide 4Acceptable Six equally emphasized channel blocks require reading before the overall reallocation story becomes clear.Topic label title; no overall takeaway
  5. Slide 5 of Claude Haiku 4.5's deck
    Slide 5Acceptable The chart omits an explicit thousands unit; its axis and data labels read as pounds, while the table specifies £k.Topic label title rather than a takeaway
  6. Slide 6 of Claude Haiku 4.5's deck
    Slide 6Acceptable Large vertical gaps separate the test-design heading, questions and bottom note, making the composition feel fragmented.Grey caveat line and grey footnote are light and small for important content
  7. Slide 7 of Claude Haiku 4.5's deck
    Slide 7Acceptable The approval request appears below the summary bullets rather than leading the slide.The decision ask is buried mid-slide at subheading size and needs to stand out more strongly
