they need to give only 1 pic to each test subject to rate.
they need at least 5000 test subjects.
they cannot know what age each pic is.
they need to have at least 8 pics of the same woman, in the exact same pose and look,with exactly a year between them.
they need at least 10 different females to do this.

and i assure you that they did not even get close to those criteria.
