G your math of course makes sense and it does seem to me to be both immaterial and irrelevant. Yet some like Hoov (who I only can assume owns Zen shares) seems to be quite concerned and aggitated by the sulpher question. He also seems to now be questioning the causitic bake process which ZEN applied. To my recollection, he was a supporter of the caustic bake at the time the result were released. I am more concerned by the strong reactions to the 'items' than the 'items' themselves. Regards CS
