Brad you are correct. In the 2011 tests, BOTH products tested at STC53, with QuietGlue Pro showing better transmission loss in some lower frequency bands as well as the critical coincidence dip area around 2Khz.

In the field we are not walking on panels to compress the damping compound. We don’t have heavy bladder presses. We have little drywall screws holding a paper-wrapped product (drywall), and not all that many of them.
In 2005 we assembled walls, securing with screws to studs, then removed the screws to view glue compression.
I wish I could let this slide, however despite specific comments to the contrary, all of the tests panels were methodically walked on. This was significant enough of an issue to the lab that it was specifically detailed in the formal lab test reports.
