Difficult? Not? Everyone decides for themselves what interests them.
I do know you can't bring fine surfacing down to your level. You must
climb up to it's level and that will take some 'homework' on your part.
A good reference, right out of their Help ...

Gaussian curvature is the product of the priciple curvatures.
As such, it's primarily an indicator of compound curvature and
'developability' (e.g. can an undistorted flat pattern be
made from the surface or vice versa).
Mean (average of priciples) or Maximum curvature are more universally
applicable for evaluating form, shape, flow. (Help mentions a 3rd
derivative analysis. I don't see it.)
Except for Gaussian Curvature, where zero is the "right" value for
developable surfaces, there are no correct values other than those
dictated by your design criteria, i.e. minimum radius. Just look at
the graduations in color. In your pic the irregular boundaries
between colors (blue to green, green to red) indicate surface
irregularities. Be aware, though, that fineness / courseness of the
analysis mesh will affect indications so if other analyses don't
correlate increase Quality. You are, of course ,just as interested
in continuity of the color regions across surface boundaries.
Each analysis type tells you ~something~ about the surface.
None of them, discreetly, tell you the whole story.
Shaded analysis range can be changed, to shift the color 'bands',
by dragging the 'pointers' on the left side of the graph or typing
values in the upper and lower 'cells'.
