Actually, Chris, I think you are right about that: in real application settings, it is difficult to tell these lenses appart. For one, the the targets, be they sports related or wildlife, as well as light have an almost infinite variability, even if we assume that one and the same photographer is doing the testing, using the same methods.
However, the "real application testing" is IMO more meaningful than shooting ISO charts and $ bills, although the latter do serve some purpose as they yield more immediate and easy results, such as they are.
