Because different people believe in different things. Personally, I believe my Factory Shop Manual, which I bought new from Mercedes. It states that the balancer, crankshaft and flywheel are balanced as a set. As a Mechanical Engineer, I know that casting variations will account for variations in crankshafts, and minimizing vibrations from secondary moments is more important in a 5 cylinder than something more naturally balanced such as a 6. As a Physicist, I know that entropy is vectorless, and reasonable efforts to minimize its increase just make common sense.

The shop foreman at the dealership could be an underappreciated genius. Or he could be an idiot.
