Could you quote from where in the report that that's what their methodology is?
I realize the report also claims to have asked Mickey Mouse himself the numbers, but it's just as likely that the numbers come from making obvious assumptions which is not very strong in my mind compared to an actual scientific survey of a random sampling for example.
"Where we do not receive specific park/
museum-level figures from the operator, we
use a detailed methodology that considers
the following: historic attendance trends
at the park/museum; generally available
information on the park/museum and/or
operator; park/museum changes, such as
new rides, areas, shows, exhibits, ticket
prices, intellectual property connections,
etc.; general economy of the nation and
the specific metropolitan area; tourism
trends nationally and in the metropolitan
area; for parks, weather trends in the
area, particularly during peak periods; the
performance of nearby parks/museums and
other attractions; media coverage about the
operator/park/museum; and select factors
as relevant."
