Who needs equations?

Scientists at the University of Bristol have come up with a 'hit potential equation' that can predict how stars, such as Adele, could get a top five hit with 60% accuracy. You don't to bother with all this science stuff all you need to ask is 'Is Simon Cowell involved?'  If Simon backs a single you know it will get into the top ten because he makes sure all his records get maximum publicity by getting them in the papers or giving them a guest spot on X-factor.
