Why it is not presentable

  • A slide the judges rated as needing work
  1. Slide 1 of Claude Opus 5.5's deck
    Slide 1Polished
  2. Slide 2 of Claude Opus 5.5's deck
    Slide 2Polished
  3. Slide 3 of Claude Opus 5.5's deck
    Slide 3Acceptable The oversized panels leave substantial unused space beneath the content, making the layout top-heavy.Both cards are sized far larger than their content, leaving the lower half of each panel empty.
  4. Slide 4 of Claude Opus 5.5's deck
    Slide 4Needs work The chart title is visibly clipped at both ends, cutting off the test description and the measurement unit.The chart title is cut off at both ends ('out test, October 2025 (four weeks): new customers per 10,000 h'), so the metric definition cannot be read.
  5. Slide 5 of Claude Opus 5.5's deck
    Slide 5Polished
  6. Slide 6 of Claude Opus 5.5's deck
    Slide 6Acceptable The table repeats exactly the numbers already labelled on the chart.The chart and the table show exactly the same data, which is slightly redundant and makes the slide feel a bit cramped.
  7. Slide 7 of Claude Opus 5.5's deck
    Slide 7Acceptable The three cards are much taller than their content requires, leaving large empty lower areas.The three white cards are mostly empty, with content filling only the top quarter of each, which wastes space.
