  4. Slide 4 of GPT-6.1 Terra's deck
    Slide 4Download slide imageAcceptable The three cards rely on multi-line paragraphs, making the supporting rationale slower to scan.The body text is paragraph-heavy in each card, so the supporting metrics (2.48 ROAS, £40 CAC, £92 vs £171) are buried in prose rather than emphasised.
  5. Slide 5 of GPT-6.1 Terra's deck
    Slide 5Download slide imageAcceptable The total row and the largest budget shifts have the same styling as every other table entry, weakening emphasis on the decision-driving numbers.The Change column has no colour or weight emphasis, so the key moves (Display −360, CRM +250, Search +180) don't stand out.
