10 BY 10, going purely by your description, makes it sound to me along the lines of Malcolm Gladwell's pasta sauce realization[0]--if you want to find the perfect sauce for person X, you need to offer chunky, spicy, and "plain". None is inherently the best, so you offer three that are best in distinct ways.
