Landing is pretty standard: threshold at 50ft at VRef, 7 seconds to touch down then max braking with full reverse to a stop. What other things will make "15% an acceptable buffer" [your words]?
50ft, 7 seconds, landing conditions as entered, braking according to chosen method (autobrake/manual-max braking/reverse), reported braking action taken into account. 15% on top of that figure. As the PIC you are free to use whatever figure you like as a buffer if you feel it is appropriate, just as you can opt to use a higher landing minima than say 200ft/550M.
