Forget the fact that 90% of Airbus pilots aren't aware of the logic of Autobrake Medium and how it affects us on a practical basis.

We seemed to have moved from accuracy to avoidance of liability.
Our flysmart landing distance is pretty accurate. If, for example, you are using autobrake low, land in the right place and leave it in until you stop you will end up somewhere between the LD and factored LD (+15%) from the threshold.
