You're adding another variable into the system by going with smaller components but exposing them to the same load as the original sprocket change. The 520 chain will theoretically wear out quicker then a 530 chain with stock gearing. Add in a gearing change and the wear will theoretically be even quicker. This doesn't take into account - Riding style, maintenance, etc.
A racer who takes care of their equipment will wear parts out less then a street rider who doesn't.
