There's only a handful of gelatin tests of the 5.7 online at Youtube - objective data that everybody can access and examine. I found two of them that aren't very complimentary to the cartridge, one that I posted. You found some that make it look better - which is fine. How many of the "good" tests were in fact cherry picked out of several tests by the folks who posted them - especially the people who sell the ammunition in the video? Beats me, I don't spend my time worrying about this stuff, normally.
The OP cited his references to back up his opinion, and you've attacked those references, which is fine. Do you have any references of your own, of sources equal or better in credentials to Roberts, who can show objective data which supports your claim:
...and I said the verifiable shootings with 5.7x28mm that I listed clearly indicate that the 5.7x28mm is at least as effective as the common pistol calibers
And it's time for me to do chores, and other productive things
