Why it is not presentable

  • Quoted a figure the analysis says not to quote
  • Left out a key finding
  • Did not give the analysis's recommendation within the first two slides
  • A slide the judges rated as needing work

In detail

  • Slide 7 quotes 6,300: the unverified 6,300-signature petition.
  • Finding missing: Holloway and Marsh Lane have the fewest visits and the highest cost per visit.

  6. Slide 6 of Claude Haiku 4.5's deck

    Slide 7Acceptable Two separate caveats receive similar emphasis, so there is no single dominant takeaway.Text-heavy paragraphs with no visual element to carry the point
