The documentation says that an SDVO command takes a maximum of 15us to be processed by the device, and that it is sufficient to read the status byte 3 times (whilst the command is still in the PENDING state) for the driver to be confident that sufficient time has elapsed. We err on the safe side and try 5 times before giving up. The only question that remains: was the old behaviour derived by experiments with real hardware? A look into the murky history of UMS, implies that the behaviour was accidental and the current retry mechanism was solely designed to catch the status byte indicating PENDING with no reference to hardware behaviour.
