I agree with that in theory... on a dyno where the tires are loaded evening yes. But in real life, on a race track with various road conditions there has to be peaks and valleys to the torque load where it's not just the engine and drivetrain dictating the load. The weight of a car, bumps and dips on the road could possible spike the torque load beyond spec.
