It looks like that study was completed in 2005, I wonder where the 2016 bats would fall on that chart.
Believe most of the 2016 composite bats come in near the upper spec.
IMO wood is less forgiving and requires greater precision to consistently produce hard-hit balls.
Big difference between swinging a -10 composite bat and a -2/3 maple/ash bat.
