Dan,

Thanks for taking the time read the blog and thanks for identifying yourself as being with HP.

If you look at the attached SlideShare presentation, it has all the data I used to build the model. I'm sorry I didn't make that more clear in the post. Let me refer you to slides 24 - 26. If you will use the full screen mode, the numbers on slide 26 will be clear vs. the eye chart in the embedded version.
