Paul, Actually it's the Gawk and repeat part I was trying to cut down on. I was hoping for some examples of building complex models in a step by step fashion that I'd be able to study for it's thought process value regarding what combinations of values worked best for what kinds of mass. I may not be explaining this properly, but if I could then I probably wouldn't need more examples in a step by step fashion. <BG> I guess I'm looking for some formulas I could plug in to cut down on the gawk and repeat cycles.
