Check out this technical summary for Escape Hybrid from the Rotunda tool site. It answers a lot of questions regarding calibration logic, etc.

Tom, that is a very good document that has been posted by myself and others within the past two years. It's always been a good document to reread as you start to learn more and more about the FEH/MMH. Most of that stuff you can't understand till you get the basic understanding of how the FEH/MMH works. All those terms they use will become better understood as you dig deep into workings of this very technical vehicle.
