Speed can be important...if in excess of 2000 fps. For typical SD handgun calibers, speed only equates to better penetration and better expansion of soft-point/hollow-point projectiles.
I don't know what you think you read in that link, but I for one would like to know in the context you're claiming.

The ONLY place in the link you posted where 2000 fps is brought up is in direct relation to fragments of a bullet at that velocity actually penetrating tissue far enough outside the direct path of the main projectile to inflict enough damage to be worthwhile. And the speed and amount at which the permanent wound cavity expands outward. Nothing is brought up in terms of a ballistic pressure wave or any other terms many wrongly associate with BPW (hydrostatic shock...).

This clearly shows you're not up to speed with Dr. Courtney's theory of BPW. BPW trauma is NOTHING like a sonic boom. BPW is pressure in psi measured at a location well beyond the temporary wound cavity produced by the projectile as it penetrates producing a pressure wave that continues traveling outside the temporary cavity.
