He gathered data on their driving distances throughout the year using data from multiple tournaments.  He looked at 35 holes from Jordan Spieth and found his mean driving distance was a 312 yards with a standard deviation of 8 yards.  He looked at 41 holes from Jason Day and found his mean driving distance was 321 yards and a standard deviation of 18 yards.
