I'm trying to say, the math on which the calculator is based IS representative of the "real world" where one or two examples are not.
A model has predictive value, or it doesn't. There have been lots of counter-examples, not just one or two. And again, the examples take place in the real world.
You can't say it's representative of the real world, if the real world keeps doing something different.
