DAYTONA BEACH, Fla. — The official margin of victory is .0010 seconds, a figure that was rounded down from .0011, which was the number that the electronic implements that calculate such things produced on its first pass at estimating the space between Denny Hamlin’s victory and Martin Truex’s loss in Sunday's 58th running of the Daytona 500. That’s the finest victory since computers have been keeping score. That’s three times faster than the blink of an eye, hardly quick enough to take in Hamlin as he nudged his black Joe Gibbs machine inches ahead of Truex’s Furniture Row car on the final laps of a race that was long on dramatic twists.
