The only way to explain this is as follows: Imagine MarketSurfer on his roller-blades, kitted out in tight pink cycling shorts, gloves and a crash helmet. He's standing on the conveyor belt. In both hands he is holding a handle attached to a chain. The other end of the chain (beyond the end of the conveyor belt) is being pulled by Jack Hershey. Jack is there pulling MarketSurfer's chain and you best believe MS will travel along the conveyor belt no matter how fast MS's little wheels spin. P1 out.
