You need stars but more importantly, you need balance. As an analogy, think of a quarter mile race between a top-fuel dragster vs. a ‘66 VW Bug. Under normal circumstance the VW has no chance of winning. But what happens when the top-fueler’s engine is even slightly out of balance? Say one of the cylinders is getting a slightly richer or leaner mixture. The dragster’s engine certainly has more power (i.e. Stars), but because of the internal disturbance, once you open up the throttle the engine will tear itself apart, ending the second half of the race in a spectacular ball of fire (or finishing 1-6 before landing backwards into the Armed Forces consolation race). From this point, the VW has an easy time of it.
I remember walking through Sproul Plaza during Spring Break in '99 (I think) with my advisor. She was being photographed on the steps of Sproul Hall. My advisor had a bad case of rubber next at that moment. A day later, she was being photographed in VLSB by the T-Rex! At the time we had no idea who she was or what was going on.
