Metabolix (I presume you are a fan of Asterix the Gaul ?),
I think that we need to have a look at the specific RTOW chart from which you are plucking figures as the story doesn't seem to be quite kosher .. is it possible for you to scan the page and email it to one of me, Mutt, or Old Smokey ? Likewise a copy of the WAT limit page for the flap setting would be helpful.
