DISPERSION CHART
The size and location of each bubble in the lower chart on the left is the average of the standard deviations for each player for a given club. Measurements are in yards.

WHAT WE LEARNED
• Distance: These are bunched tightly in carry distance, falling within three yards of one another. Three of the four models are within one yard of each other for total distance.
• Trajectory: The TaylorMade r7 CGB Max has the highest ball flight, followed by the Nike SQ Sumo2. The Callaway FT-i Squareway flies lowest.
• Control: The Nike SQ Sumo2, followed closely by Callaway FT-i Squareway, provides the most directional forgiveness. The TaylorMade and Bobby Jones woods offer a good deal of help, too.
