Framer is correct. The Biz Jet flight plans typically offer several diffeerent scenarios. My comments were directed towards AC120-42A which while being somewhat dated, is still the basis for the Boeing ETOPS diversion flight planning management. Framer is also correct when he says that the two engine unpressurized at 10,000 will usually burn slightly more that a 1EO diverson.
Google AC120-42A and take a look as there is a lot of good material in there.
