FAA QRH distances i believe are unfactored,JAA are.
Same as JAA include line up distance for torr,faa uses from brake release point.
Different regulatory bodies,different calculations...
ALWAYS calculate your landing distance,it avoids choosing inapproriate a/b settings,position awareness in low vis,and be confortable if last minute change to a shorter runway or if weather/runway conditions changed since dispatched.
Learn your extra distance based on your every day skills..
