You also have to account for having the testers show up to the race (likely flights and hotels) and handling the samples in a controlled manner. I bet there is a set fee of a few thousand just to have testers show up, plus extra for each sample tested, but I'm just guessing. Still, I'm for the increased fee even if it means testing at just a few more races.
