Forum:Jackes Compass

According to the Pirates of the Caribbean Timeline, Barbossa mutinied against Jack 10 years before Curse of the Black Pearl. It also states that Jack received his compass 7 years before CBP. However, the article on Jack's compass says that he used it to find Isla de Muerta. But if that is true, then he either would have received it three years earlier or the mutiny occured three years later (which, according to the films, is untrue.)Could some clarify this for my?
