Have a look at the rear sprocket profile Paul. Some are manufactured flat on one side -the face that's bolted to the wheel and have the face of the teeth cantered in on the other side -a bit like an old dished dustbin lid. If yours is like this then inevitably the flat side will show wear -but the other side will not because the sides of the teeth are not quite touching the chain sideplates.
