  1. Slide 1 of Claude Sonnet 5.5's deck
    Slide 1Polished
  2. Slide 2 of Claude Sonnet 5.5's deck
    Slide 2Acceptable The middle card's wrapped heading pushes its highlighted figure below the figures in the adjacent cards, weakening alignment.The lower half of all three cards is empty, so the cards look under-filled
  3. Slide 3 of Claude Sonnet 5.5's deck
    Slide 3Polished The 5.12 data label sits almost on the chart title, which looks cramped
  4. Slide 4 of Claude Sonnet 5.5's deck
    Slide 4Acceptable The right-hand explanation is text-heavy, particularly the long final bullet; its key point is not visually distinguished.The chart title crowds the 18.2 and 17.9 data labels
  5. Slide 5 of Claude Sonnet 5.5's deck
    Slide 5Acceptable Both grey panels have large empty lower areas, making the layout feel oversized for the content.Both cards are roughly half empty below their bullets, which wastes space
  6. Slide 6 of Claude Sonnet 5.5's deck
    Slide 6Acceptable The title leaves 'yet' alone on its second line.The table and bullets occupy only the top half of the slide; the bottom third is empty
  7. Slide 7 of Claude Sonnet 5.5's deck
    Slide 7Acceptable The table does not visually emphasize the display reduction, major increases, or total; viewers must scan the figures to find them.Nothing in the table highlights the display cut or the big increases; the Total row is not emphasised
  8. Slide 8 of Claude Sonnet 5.5's deck
    Slide 8Polished Both panels are about half empty below their bullets
