For the 10 Hz update rate, channels should be logged at 20 Hz even
though they only update at 10 Hz. This will help minimize the time delay
between when the data arrives to the logging device through the serial
stream and the moment the values are logged. For the 20 Hz option,
those channels which update at 20 Hz should be logged at 50 Hz. GPS
Date should only be logged at 1 Hz. See the table above.
