Surely the next test must be running their algorithm against a completely new set of test books, and seeing if the can identify the popular ones in that set.

Agreed, if they are really onto something, they should be able to use this to predict which new books should be popular. There are a number of alternative explanations for why they got these results with PG books. If publishers were to adopt this algorithm when they select books, then authors would face pressure to tailor their books to match the algorithm. This could lead to books becoming more similar, and we ought to at least find out if it really holds up first.
