The official Boeing Flight Crew Training Manual has a nice diagram with the increase/decrease in stopping distance, from an RTO at V1, for various cases such as not selecting spoilers, or using one thrust reverser during deceleration.
As we know the normal RTO distance is based on full brakes and spoilers only, no reverse. In the same situation, adding the use of one thrust reverser only decreases the stopping distance by 120 ft. Therefore why bother with more than reverse idle when only one reverser is available? I am, of course, refering to the landing case where there is a big safety margin built into the figures.
