Isn't the use of Databases in general back fitting. Finding out what has been successful in the past? Looking for the optimal settings would require doing just what you mentioned Head, but that would be 20 raised to the 10th power iterations I think.
What I was thinking about is everyone has some idea of what factors are important or ones they like to include. Bu doing as I said, they could test out their factors and different point settings for those factors until they found the best setups for their particular factor set.
Anyway that is what I had in my head. But as I said I am looking for as much input as I can get before I start the design and then the coding.
