I am sure the publishers had an interest to conduct their "studies" to justify the 26 average. If you select the right data and extrapolate you can make anything happen with statistics. Even the video is flawed in that aspect as the five books may just be exceptionally well treated books. It would be more meaningful to look at the last xx amount of books (e.g. 100) that were beyond repairing and see how many checkouts they had.
