Maybe with the new "horsepower" Nirvana will give us we'll come up with something. Excel is pretty limited, even with 30 hour macros... Focusing on one year was just a way to limit the variables while I was experimenting. I like to isolate one input and then run it through a bunch of iterations to see which things are affected & how (brute force vs Steve's finesse). It's actually nice we have so many different types of markets the past 8-10 years to test against (or over). Mark |
