Jim,

I rather doubt that the controller is non-linear and, the more I think on it, it does not matter. This non-linearity does shed some light on some phenomena I saw working with autonomous mode last year. I'm thinking a lookup table to linearize the output may be in order this year.

Once again, Thanks for sharing the data.
