Is the radar exactly the same distance from the gun? He also brings his hand forward and shifts the arc when shooting from the bench. These variables will also account for a 20fps difference in muzzle velocity.
His experiment is repeatable so I will do the same and post.
Notice the low-mounted tripod to maintain consistent Radar Field of Regard for projectile tracking. Same tripod set-up for on top of the bench, as well as the ground. Muzzle position didnt change on the bench, and the fps difference was also observed on the bench shooting with vertical torso vs choked up/recoil-managed torso.
The Radar track just confirms the known applied physics though. A vertical brace of variable resistance will have less resistive force to an arched brace, or an aligned brace behind the recoiling mechanism.
You see it especially in CQM stance.
