  2. Slide 2 of Claude Sonnet 5.5's deck
    Slide 2Acceptable All five bars have identical styling, so the key comparison between the business-case assumption and adjusted pop-up sales is not visually emphasised.All five bars share one colour, so the key comparison (business case £2,917 against pop-up adjusted £2,380) is not highlighted.
  3. Slide 3 of Claude Sonnet 5.5's deck
    Slide 3Acceptable The decisive 36-month threshold is stated in text but not drawn on the chart, making the pass/fail comparison less immediate.The chart has no reference line at the 36-month board rule, although the title and the chart heading both hinge on it.
  4. Slide 4 of Claude Sonnet 5.5's deck
    Slide 4Polished The '74%' data label on the Leeds bar collides with the 'Staff turnover, FY2025' chart title.
  5. Slide 5 of Claude Sonnet 5.5's deck
    Slide 5Acceptable The three cards are substantially taller than their content, leaving large empty lower sections.The lower half of each card is empty, so the cards look oversized for their content.
