Ken is not being shy, he just doesn't have anything new to add. ;-)
Have found nothing that clarifies if damping in FFB settings is
applied the same way as it is in control systems or how it is used (or
not used) by the software. Don't have any way of verifying if the
suggested settings are correct. Unless someone has come up with a way
of measuring the forces at the wheel and comparing them to the forces
being requested by the software then whether or not the forces are
correct for given settings will be subjective.
