Oops, I forgot to copy this to the list, JimC
Mark, needless to say, I couldn't resist and took a moment to glance at your webpage (my busted car can wait a few minutes). I liked the page and will look closer tonight. I do mention in passing that based on the relationship between the proximal humerus & dp crest with the scapulocoracoid in Qsp and using that and the Qn humerus to project the scapulocoracoid for Qn, I'd expect the Qn torso to be similar in size to that of a pro football player albeit a large football player. In other words, the torso would be expected to be much, much smaller than you project. I don't have enough info on your technique for mass estimation to know if that would impact your wieght estimate. I'd like to chat more with you about it, if you have time.
Jim

Hi all (particularly Jim),
"My projection of 150 Kg is based on optimal CL for the aspect ratio that I generate, and his is based on Mark's estimate (which I haven't seen -- can anyone send me a copy of Mark's calculations or summary ? )."
A brief overview of my mass work can be found at:

It's entirely irreverant and informal, but it should give you some gist of where I'm coming from. The slightly less informal paper is in review at the moment.
So long,
Mark
