I'll assume you meant "shift" and not taking a dump...

To be able to assess the accuracy of your statement, you need to specify the redline and gearing of the assumed drivetrain.

IMO, based on my calculations, the stock N54 power curves have sufficient drop off in the upper rev range to warrant a shift before redline in the higher gears to maximize acceleration.

anyone who disagrees with the above is simply wrong, as they can't prove anything otherwise (and conversely, proof in abundance for the CORRECT case)
The term "moment of force" (sic) has nothing to do with the notion of time. The term "moment" refers to the perpendicular distance of the force vector to the point of reference. Torque, moment of a force, couple are all synonyms to define a twisting force.
