Would your strategy really differ all that much? Accelerate as fast as you can. That last 1/2 mile goes by pretty darn quick at these speeds. The Lambo in this vid is significantly faster at every split.
How much is gearing at play in these cars? Does the Gallardo have the gearing to finish out a mile at 280? What do the FGTs look like? The video I just saw had M2K's car doing 280mph and they basically just put off the line until 3rd gear it sounds.
