Chan won't skate clean. He still will get higher PCS if he zambonis the ice. Dai or anyone else, even if he skates clean, won't get higher PCS than Chan. It's according to your logic, i.e. based on facts from recent competitions.- Chan will get higher PCS if he skates clean (or close to clean), and the same with Takahashi (who, if he's clean, will even get higher PCS than Chan).
