The rules are that the speed have to be measured as an average over 10 secs on a GPS unit like the speedpuck or similar. Then a third party have to verify the reading.
Tony, what you suggest makes it a bit more difficult to get the reading verified by a witness/third party that was present? Since they specify that the speedpuck "or similar" is to be used I guess this unit already have the speed over 10s average built in?
