You can never be completely sure what an appellate court will focus upon in rendering its decision. In the Sopranos case, Baer v. Chase, 392 F.3d 609 (3d Cir. 2004), we focused 75% of our 60 page Brief on breach of implied contract, with only a 1-2 pages focused on quasi-contract. The Third Circuit affirmed the District Court completely, except, much to our surprise because we thought implied contract was rock solid, the Third Circuit reversed on grounds of quasi-contract.
Accordingly, as long as it does not undermine the overall presentation, it would have been prudent to find a way to get the statistical information in the Reply Brief, even as a footnote, posting the link with a request that the court take judicial notice of the Bhatt Report's publication.
