Remember the QRH Normanl Configuration Landing Distances are calculated to STOP.
So, if you are planning and briefing to take a high speed exit from the runway you may in fact pull up short of the exit with no intervention. This is a common misunderstanding on the line.
If you are landing on the spot, on speed you may need less autobrake than you think if using a rapid exit. Experience on the line will help fill in the gaps for sure.
