The Max Radius option in CurvatureAnalysis does not work properly for regions of surfaces where the Guassian curvature is negative. It shows red representing the top of the scale in those regions, independent of the scale and the actual maximum radius. The Max Radius option appears to be working properly in regions where the Guassian curvature is non-negative, displaying the color code corresponding to the principal radius of curvature with the largest magnitude (ignoring sign of the curvature).

The Min Radius option appears to be working as expected, displaying the color code corresponding to the principal radius of curvature with the smallest magnitude (ignoring sign) everywhere.

The attached file contains examples of surfaces with Guassian curvature non-negative everywhere, surfaces with Guassian curvature non-negative in some regions and negative in others, and surfaces with Guassian curvature negative everwhere (except for isolated points or lines).

This problem occurs in both V5 and V6 WIP. I posted it here in hope that it will be corrected in V6 before it is released.
