Unless things are quite broken, why would there be less to do? It seems that the amount of work to do depends on the amount of data stored (and data transfer rate) since the scrub's task is to read all of the data and make sure that it is consistent. If my math is right, it seems that scrub on my drive array proceeds at about 15.2GB/minute (259MB/second). It would be interesting to see what typical scrub rates are for various scenarios.
