  1. Slide 1 of Claude Fable 5.1's deck
    Slide 1Polished The recommendation wraps with 'price' alone on the second line, creating an awkward orphan.
  2. Slide 2 of Claude Fable 5.1's deck
    Slide 2Polished
  3. Slide 3 of Claude Fable 5.1's deck
    Slide 3Acceptable The chart, table and explanatory bullets repeat much of the same information, making the slide more text-heavy than necessary.The table repeats the two numbers the bar chart already shows, which crowds the right side.
  4. Slide 4 of Claude Fable 5.1's deck
    Slide 4Polished
  5. Slide 5 of Claude Fable 5.1's deck
    Slide 5Polished Similar to slide 3, the bars are extremely wide for just two data points; space could be balanced better.
  6. Slide 6 of Claude Fable 5.1's deck
    Slide 6Polished
  7. Slide 7 of Claude Fable 5.1's deck
    Slide 7Acceptable The comparison table uses long, similarly weighted sentences, making the decisive differences slower to scan.The table is text-heavy with no visual emphasis showing which option wins on each row.
  8. Slide 8 of Claude Fable 5.1's deck
    Slide 8Acceptable The recommendation is repeated in the title, numbered actions and bottom decision statement, adding text without a new visual contribution.The grey 'Two numbers not to lean on' box is about half empty at the bottom, which unbalances the layout.
