This seems like a good thread to mention the Principle of Charity.
If there is a problem with the setup that results in the reported values being measured too low, that is probably something best resolved by independent testing or examination of the setup, not accusations of dishonesty. Given that T&K is paying for independent testing from Pew, I expect we will get accurate values that make sense before too long. And if there is something that can be done, in the meantime, to independently check their testing setup, I'm all in favor of it. But it's not like anyone "needs" to buy one of these suppressors right away, and I get a good feeling from T&K's posts that they are open to outside eyeballs looking at their setup, so I expect that any issues can be sorted out fairly easily.
