Well, we take - we do different types of interviews, interviews in individual interviews which tend to be much longer and detailed, we also do interviews in groups, sometimes with, you know, small groups from three to five, seven people. So we don't - we wouldn't necessarily afford the same amount of, how can we say, detail and information obtained in a group setting as that obtained in an individual interview. It's hard to know - at any rate to give a precise number of the amount of individuals interviewed for this particular report. Again I wasn't involved in it. I can be more or have more information about my own reports.
