The key to winning Superstars had become to gain maximum points in your best events and then to place as highly in the others – simple in theory, but appallingly hard in practice. Jacks usually dominated in the gym and weightlifting, and almost always also won the cycling and canoeing. That gave him a nominal 40 point head start on his rivals, but if this sequence could be disrupted, then Jacks was relying on picking up more points elsewhere. He never competed in the two running events and was a weaker shot that his rivals, so he was then faced with winning the basketball or swimming which were much more equal events. And in the Challenge of the Champions Keith Fielding was able to disrupt Jacks' strategy by enough to beat him.
