Settings include:
•
MAX: Used when minimum stopping distance is required. Deceleration
rate is less than that produced by full manual braking
I think it was already discussed somewhere recently that deceleration with landing auto brakes is different than RTO auto brakes.
Landing autobrakes(let’s assume max) will release brake pressure if the braking plus reverse thrust exceeds the selected deceleration rate.
RTO autobrakes is maximum possible braking plus whatever other slowing down capability, such as reverse, is used.
Therefore, the information you quoted, which mentions that you are choosing a fixed artificial deceleration rate versus a maximum deceleration rate, seems to not be applicable.
