How many records can a stamper press?


For instance, MoFi numbers their records. I just purchased the 45 RPM MoFi release of Brothers in Arms. I have number 8,146. Does a manufacturer like MoFi replace their stamper (typically) every 1,000 pressings? 2,500 pressings? 10,000 pressings? Does a manufacturer like MoFi have a standard?
