On heavy for jet aeroplanes that tend to use an awful lot of runway the procedure was changed in the 1950's. Holding the stick back and accelerating with the elevators up would increase the drag once they get some effect but not enough to lift the nose. Lifting the nose wheel and waiting for the aircraft to lift off also slows the acceleration.
The technique arrived at was to let the controls stream until about 25 knots before the calculated unstick and then rotate the aircraft so that it unsticks at the desired speed.
far more gentlemanly; or should I say personably.
