Why it is not presentable

  • Did not give the analysis's recommendation within the first two slides
  1. Slide 1 of GPT-6 Luna's deck
    Slide 1Polished The '£350,000 a year' callout is set larger than the slide title, so the two compete for first attention.
  2. Slide 2 of GPT-6 Luna's deck
    Slide 2Polished
  3. Slide 3 of GPT-6 Luna's deck
    Slide 3Acceptable The table occupies only the upper-left area, leaving a large unused gap beneath it and an oversized explanatory panel on the right.The table shows only three of the nine libraries, while the callout's claim refers to all nine.
  4. Slide 4 of GPT-6 Luna's deck
    Slide 4Acceptable The title introduces a comparison but does not identify a single takeaway; viewers must read the assessment column to find the key distinctions.Roughly the bottom third of the slide is unused white space.
