People not understanding something does not minimize it's value. This is pioneering research, a serious and important contribution to the hobby. Collectors need not apply, this info is only of use to shooters.
To get the ball rolling on this, the stats for commonly available guns could be published. A selection of target O/U guns, some SxS guns that can be purchased new and available in a large dealers rack, and even some common trombones and autoclackers. Go handle the guns, shoot some that belong to others, and you can start to correlate the measured values with what you prefer in a gun for a specific use. Your trap gun will not measure the same as your quail gun.
Don's system is not complicated, and should interest any serious student of shotguns.
