What is the standard deviation of interrupt latency on the DCD pin on the serial port. Perhaps some one who has a "pi" could measure this. All the data should be in the system log as each PPS is time stamped and written to the log. If the DCD pin is polled you are not going to get decent results. Maybe someone could read the PPS drive code.
