CASA caused this drama regarding looking through the FD and reducing speed, with respect to instrument rating checks and the requirement to fly V2 - V2+5. It is rubbish and not relevant to the aircraft operation.
The Boeing manual clearly states how the FD commands pitch for speed depending on the time of the failure. The commands result in a profile that meets take off performance.
Special procedures may be designed around separate criteria, but they will be listed if flying the normal profile does not meet the criteria.
