Fractional. The difference between Brazil humiliatingly losing the first game of the Copa America Centenario against Ecuador and escaping with a 0-0 draw.
So fractional that the latter happened at the Rose Bowl in Santa Clara, when it should have been the former.
Miller Bolanos' effort from the byline was fumbled in by Brazil's goalkeeper Alisson at his near post; it was an embarrassing mistake, but not one for which he was made to pay.
The officiating team deemed the ball to have been fractionally out of play before Bolanos fired it in, although replays indicated that the whole sphere did not cross the line.
