I think the main point here is, that if the guys had been able to hit the tarmac in the correct spot, we would not be reading about it. As they would have stopped with some 300m remaining, using medium autobraking. If they they had used max manual braking after touchdown in the correct spot, they would have 700m remaining. All this at Max landing weight (not sure what weight they were at), and 10kts tailwind (twice what has been mentioned). I think this shows the importance of stabilised approaches, and maintaining the correct touchdown point, rather than the implications of pre and post dispatch performance figures. This accident was preventable right up to the point of touchdown.
A good lesson for all of us I should think.
