Level III+ Armor Stopping .50 BMG Bulletsth

After a long break, Jerry Miculek resumed creating and publishing videos on his YouTube channel. There is no doubt that most of our readers know who is Jerry Miculek and that the content he creates has an overwhelmingly high level of coolness. In the latest video published on the channel, Jerry tests a Veterans MFG Ultralight Level III+ body armor by shooting a .50 BMG Hornady 750 grain A-Max bullet at that plate. Enjoy the video.
Yes, as unbelievable as it is, this body armor managed to stop the .50 BMG bullet at such a close distance. Now, I understand that the penetration largely depends on the projectile type and a high-explosive armor-piercing incendiary projectile would probably zip through and tear apart this armor plate. Nevertheless, the fact that it can stop any .50 BMG projectile is really impressive. This plate basically stops a bullet that it is not supposed to stop. That being said, it is unclear to me why isn’t this plate rated Level IV? Is it possible that despite being capable of stopping a .50 BMG A-Max bullet it will fail to stop a .30-06 Springfield AP bullet thus being unable to qualify for Level IV?
