RE: insuti testing
There are a host of problems with blotter layers as they let moisture freely travel under the slab.

Installed perfectly they would work well but cause the concrete to dry more slowly.

But they are never installed perfectly. A puncture in the vapor retarder under a blotter layer will allow a huge amount of water into the blotter layer, whereas a hole in a blotter layer directly against the concrete will be nearly insignificant.

As far as RH testing goes, you need to reference the conditions assumed and indicate the requirements set forth by the flooring manufacturers and ASTM F-710. If the moisture levels change due to improper construction detail or workmanship error, you can hardly be held liable.
