Yes. We check very closely to what degree we can, with external datasets about the representativeness of the information. You might have seen our business barometer survey, which is sent out to a different group of members every month, and we get very consistent results back. So in terms of the statistical variance we get in these samples, they tend to be within the bounds of the private sector market research industry in that respect.
We do publish those kinds of bounds of confidence as well, and we take it very seriously to make sure our information is as representative as possible.
