Very easy to use.  Yeah, there is still the issue of the fudge factor that needs to be fixed.  I wish I could tell you how to fix it but I don't know how without spending a lot of time looking at the equations etc.  Regardless, the instructions are clear and anyone picking this up would be able to use it.

I walked him through how to enter the month and "fudge" numbers.
