11 years later and now I have bought Serge's Discus. Udo, if you have your ears on, are the R. Johnson numbers from his 1986 article? The way I read the article he tested at 700 lbs which is 30.2kg/m^2 rather than 32.

thanks

Nick, I'm sad to inform you that Udo died a few years ago after a lengthy illness.
