As an interesting point, it might be better to allow cost| or |cost-Sam and generate the other. Since I have Sam already, I have to convert back when I'm adding pages, and my guesses weren't always correct, until I had data for comparison. I think what I've found is that |cost-Sam = CEILING( cost| * 0.9 ), so to convert back you have to use |cost = FLOOR( |cost-Sam / 0.9 ).
