From the video #236, the first aircraft starts after ‘the line’ (‘2’), the second from behind the line; why the different ground roll … mass ?

The leaked video appears to have a shorter ground roll than both.
Once again SHAR info. Min distance was dictated by min ramp exit speed required to fly away (about Vs/2 on a 12 degree ramp). Max distance was dictated by stresses on nose wheel leg during ramp entrance and exit. Starting the roll anywhere between min and max was OK and would be decided by the FDO dependant upon deck utilisation.

I suspect that the same applies to Dave.
