If you took it to be anything more than the general statement that it was intended to be, then you read far too much into it.

Interestingly, the +P+ 9mm, 357 magnum, 357 Sig, 44 Magnum all achieve 1300 - 1500 FPS. I believe that this affect will be seen at anything over 1000 to 1100 fps (the speed of sound) and especially when you reach above 1300 fps. These handgun rounds do not seem to perform well in gelatin, but perform well consistently on the street.
Nothing in that document disagrees with what I said- it has already been established that rifle projectiles at typical service rifle caliber velocities are capable of producing TC large enough to damage tissue.
