I think you will find that the takeoff performance figures are predicated on having takeoff thrust set within the line up allowance
Be very careful about this, it not only has to do with the model of aircraft, but also with the software used for calculating the takeoff weight.
We use two versions of Boeing supplied and approved software. The older version doesnt have the ability to account for line up distance, the new version does, but doesnt work on a mainframe computer.
Its best to check what your airline policy is regarding the amount of line up distance used in the calculations. BTW, we operate under FARs.
