To establish these tests, we use committees of experts, groups of specialists. I want to make sure there is absolute confidence in our assessment methods. I am providing a total all-in cost. My costing includes the time of the people who develop the test, the time of the experts who assess the test, and the cost of the pilot test. There's one test with four versions. When I replace the one version, it is not $1 million; it would be only one quarter of that cost. If I run out of the four versions, then I'm back to doing a totally new test. It is a function of totally costing something. If I gave you a marginal cost, it would be a much lower number.
