I'm actually not sure it is predictive yet, but I am not sure how much that matters. It is more useful for validating reality as it currently is today - startups are anything but reliable when it comes to generating consistent growth. I would imagine the later the stage, the closer to predictive this becomes but I wouldn't make any future claims on outcomes based on this. I think you could probably use it to determine the next round of funding though, so it is useful in the short term.
