The formalism of QM says precisely nothing about any given experiment that is performed once. It is only when a given experiment is performedGeorgCantor said:but if everytime we do a measurement/observation we get an accurate result that exactly conforms to the calculations

*an infinite number of times*that the quantum mechanical "prediction" is said to have been finally realized.

This also means that if a given experiment is performed any finite number of times (no matter how large this number is), then there is not any kind of purely "quantum theoretical" statement that can be made about it.

It is for the reason that infinite experimental trials must be performed within the formal theory of QM that it can

*never*, strictly speaking, have any kind of applicability to the universe of "real world" experimentation.
