Why it is not presentable

  • Did not give the analysis's recommendation within the first two slides
  • Drew a conclusion from a figure without its caveat
  • A slide the judges rated as needing work

In detail

  • Caveat missing: respondents were mostly weekly users (82%, against 21% of card holders), not representative of residents.

  6. Slide 6 of Gemini 3.1 Pro Preview's deck
