Is there much change in SSS with higher RGB values?  The RGB values suggested return a combined color of white; if all values for those channels exceed 1, you will get white as a SSS tint.  I agree with the higher values enhancing translucency but those arbitrary values are unnecessary because the channel range only goes from 0 to 1.  As I stated, any value above 1 across all the channels just gives you a white tint.
