I would have thought it would be more of a concern near gross. I am assuming that the intent of the accident investigators is the concern about wasted runway when doing a rolling takeoff or perhaps more specifically that some pilots might waste more runway than others depending on the rolling takeoff technique used.
Concerning rolling takeoffs, the report stated "However it is clearly less precise, and if the aircraft needs to turn through a large angle at slow
speed, possibly using asymmetric thrust, is then allowed to move slowly forward while thrust levels are balanced and then throttles advanced, valuable runway distance can be used before take-off power is established."
