Certain models are inherently useless. If you use a Taylor series to model a sine curve, you can get arbitrarily good results over an arbitrarily large range, yet the model will always fail catastrophically when the modeler wants to figure out the value that will give sin(x) = 2. This seems like a system designed for the analyst who wants to make sin(x) = 2, and will blame the participants when reality doesn't match the model.
