For this study, an initial run recreated the \n1988 \"truth\" model.  The true model was then simplified to account for information \nnot provided the participants in the 1988 calibration exercise. Increasing sophistication \nwas brought to bear to demonstrate how problems identified in 1988 were overcome \nusing modern software approaches.
