Dunno if serious.....

Can you tell that your predictions are already grossly off? There is so much wrong with it that i don't even know where to begin. Its like a prediction someone will make if living under a rock or in a bubble of some sort void of any kinda statistical or historical analysis whatsoever. You have to be joking right?
