Mr Heathrow.
Yup.
Done that. (Twice). I can b.s. my way on stats. So can Thiefrow's owners.
The CAA interviewers, (if they have any now - I think it is subcontracted out) do not interview 1500 people, so cannot be used to cover the many millions that the report is s'posed to cover.
And, er, how many of the connections are in the early hours as the planes come in from Asia and Americas? How many interviewers around then?
Plus, the Interview intentions questions used for Elections are much less complex than the data required for that report.
But you haven't paid for the 10 minute argument.......
