What makes Arm C1 different

  • • Eight of the nine boxes are Arm B, word for word.
  • • One box changed: it asks what would change the farm's plan.
  • • Same treatment for two diseases? Then do not spend a question.

It was the best one we measured

  • • Right 77 times out of 144, where Arm B got 74
  • • Wrongly flagged a must-report disease 30 times, where B did 46
  • • Asked 3.84 questions a case, where B asked 3.58

And it is switched off today

  • • Turned off on 22 Aug: missed must-report cases went from 6 to 9
  • • Its engine runs from a pinned copy, kept apart from this tree
  • • Research only. Nothing is deployed.
