When the take-off run available (TORA) exceeds the calculated accelerate-stop distance (ASD), then only the number of RVR values relating to the ASD must be at or above those required in the table above.
Bit of a different way of saying whats in our Pt A :-
When the last third of the runway is not required for rejected takeoff
performance purposes, a minimum RVR of 75 metres must be
available in that segment.
