Yes, I am. We are working on the answer to the precise question that the OP posed. And no, the answer isn't in print anywhere.

I am working with Eric Farmer and Gronbog, and I'm confident that we'll have answers. If the study, along with another than Gronbog is doing with Tarzan, proves interesting, I am thinking of adding another appendix to BJA3 and publishing the findings when the book is reprinted early next year. This is computationally very intensive, so don't expect a quick result.

Stay tuned!
