I originally looked at BRIS Prime Power to see if I could find some factors contained within it that weren't obvious that I could use to develop my own method. I didn't find anything like that so I took a different approach. But, someone else may find things that I missed. There is some value in there somewhere because the top 3 ratings lose much less than average.
