Lighter grip: 116 to 144 yds, same swing
The coaches compare the data from two swings of the same length. With high grip pressure the first swing measured 116 total distance and 84.4 mph ball speed; with lighter grip pressure the same-length swing jumped to 144 total distance and 99.5 mph ball speed. Their point: at the same swing length, lighter grip pressure effectively gives you more distance.
