This is a known issue that Ken is aware of. A recent fix to the auto-focus Quadratic fit routine to allow it to handle very large positions caused a rescaling of the Quadratic fit parameters that the SGP Autofocus Viewer uses for plotting the curves. It will be fixed in the next release.
Many thanks for the update. I look forward to the next version. Meanwhile the temp coeff graphs look good.
And finally, just to add my thanks to all who have worked on the AF changes. I am finding that the HFR/HWFM stats for my subs since the changes are much more uniform.
