We're almost at 3lbs MVER, so what if the rH is over 90% ?

Yeppers.

RH "at depth"= less affected by ambient conditions. Once you drill that hole you're not having to worry about a bunch of other factors.

That said, F2170 still needs to be read carefully. I've already clued up some contractors on the requirements, and the colour drains from their faces
The Aussie flooring industry has finally dragged itself up to the USA level of knowledge- our resilient standard now specifies in-situ RH, but unfortunately also allows for surface RH with the hood, which means we'll be doing tests which will take AT LEAST 72 hours....plus a few days... "how long is a piece of string" So these ambient conditions we're discussing here will be more of a factor.

Speaking of the hood, I've got a fuzzy question for Jason on another thread.

Now I'll let you guys go on and have another MVER debate ...
