The point being missed here is the difference between the demonstrated performance of the -800SFP (and for that matter any aircraft) and the factored performance. It is the factored performance that is required for airport and route planning together with pre flight planning on the day. The incremental factor is 60%. As an example it follows that if an aircraft can be scheduled to land on a 1600m runway at a given weight, the demonstrated landing distance will be 1000m. The line pilots may not wish to emulate the Boeing test pilots who generated that data but there remains a big gap between the two figures of which advantage can be taken.
So I am not the least surprised by the observations from SEN. It is what is to be expected. The whole purpose of the factoring is to ensure safety margins in day to day operations. Anyone expecting to see the -SFP only just stopping before the end of the SEN runway was bound to be disappointed.
