At that rate, the whole HP 41 production would have taken less than one year.

The assumed numbers peer week seems to be a bit on the high side.

Since the beginning of 1975 when HP moved to effective production Month then production Week in the serial number, the serial number range is common for all models, which means that ~45000 hp calculators (or may be hp products overall?) have been produced in Singapore this week, it doesn't mean that it was only HP 41 units.
