For a 235 ton landing weight I found this info. For what I will call a normal landing the required runway was 5615' using max autobrake while max manual braking had a significantly shorter requirement of 4462'.
If autoland was used, the max autobrake setting increased by around 300 feet to 5918' but, the max manual braking distance increased by almost 3000 feet to 7301'.
Why so much?
