Wow! That's a great thread. Explains SSS like nowhere else, & probably should be included in some documentation, if that effort is still alive, and if still true for recent versions. I don't remember ever seeing it. Even with that info, still seems like SSS requires much experimentation, tweaking based on model geometry, chor lighting, and model's size.
That is a great thread. Too bad those Bradbury boys went off to college...
