I completely agree that without a full survey (in this case - in some situations sampling may be adequate) the results will be inconclusive. And it is hard to imagine that they will be without bias too. But from what I have seen so far, it appears that the bias has been reined in, and the current conclusions seem to be fairly accurate.
Agreed
