Gauge/Gravity duality and evidence for superstring theory

    I don't know much about gauge/gravity duality but I know that its a conjecture coming from superstring theory and one of its examples is AdS/CFT duality. Now I have two questions:

    1) As I said, I know that gauge/gravity duality and superstring theory are related but I don't know how much. Is it enough relationship to imply that if gauge/gravity duality predictions about QGP, superconductors, etc. agree with experiments, then these can be counted as experimental evidence in favor of superstring theory and if they don't agree with experiments, these can be counted as evidence against superstring theory?

    2) I've read about another example of gauge/gravity duality, Kerr/CFT. Is it as accepted as AdS/CFT(I know AdS/CFT is itself still a conjecture but people are using it anyway)? Is there any other example of gauge/gravity duality?

    Thanks

    There are various arguments for validity of gauge/gravity correspondence. Some of these arguments are based on string theory, but other arguments are not. Thus, if gauge/gravity correspondence predictions about QGP, superconductors, etc. agree with experiments, that cannot be directly taken as experimental evidence in favor of string theory. Likewise, if they don't agree with experiments, that cannot be directly taken as experimental evidence against string theory.

    Another general comment. The notions of gauge/gravity correspondence and gauge/gravity duality are usually considered to be synonyms. I think these two concepts should be distinguished:
