Bill Munn's work is a veritable thesus on the PGF. Gigantofootecus and Sweaty Yeti have also done groundbreaking work. Have you reviewed their work here on BFF especially those related to Patty's proportions? Look for ASH ratio and arm proportions. Some of GF's work dates back to ~ November 2005, in BFF 1.0 archives, which is about when he began posting here, if memory serves me.
I'd say a very strong case has been made by all three. Can you name me anyone who has successfully explained Patty's inhuman ASH ratio and Gigantofootecus' photogrammetric analysis?
