It seems it would be valuable to latch the Maximum-Rudder-Deflection (Port and Starboard) achieved into Pypilot statistics-panel.
Also make it resetable.
This can be used to adjust AP servo-gains; providing a feedback mechanism of effectiveness.

I am not sure what you mean "latch" but the maximum rudder deflection angle can be set by the user already.
It is possible to make the autopilot more accurately move the rudder at the right speed (calibrate speed from command vs current draw), as well as automatically set the gain as you say based on the rudder feedback if it exists. Also possible to have an autopilot that commands the rudder in absolute position.
All of this is planned for the near future to play with, and it does as you say get a better starting guess for the gains.
Still the type of boat and desired steering will ultimately determine the gain setting.

What about an enhancement to the dashboard rudder display which allows a time-lapse of rudder positions in different colors over the past minute or so?
Also could plot the rudder deflection on one axis, and how often on another axis for the past few minutes, it might be interesting to look at.
