You read me wrong, IC. The FMS took the THY all the way down the runway, almost resulting into RNAV autloland. The fact of the aircraft landing on the runway edge was blamed on the THR COORD being wrong (they were). What I mean to say, is RNAV on modern day (Airbus) A/C = precision within 10 m. Sorry for the confusion.
