Yes Howard, it's the Feiten system. Not to beat on that one too much, but it's one of several systems I was going to make spreadsheets for. Now that I have most of the formulas laid out, I'll probably switch the references and variables around to make some for systems like Earvana and others. It's just a neat and easy way to immediately view the effects (in reference to standard intonation) of small changes in different areas.
