The point is not lost on me. Certainly tort law, contract law, administrative law, and many other areas of law aren't usually sourced from blackletter law as much as from jurisprudence or other sources of law. I think this very point you're trying to make would be more persuasive if the analysis had modelled the relationships that do exist between blackletter law and case law. As we have already discussed, text similarity may not suffice to reveal these relationships. And while these relationships don't always exist, when they do exist they are very strong.
