gonna make?

Your observation is correct. The reason is because you want the
finish floor and the subfloor you're fastening it to to have roughly
the same moisture content so they'll expand/shrink together. The
expansion/contraction may be tiny... less than 1/4" over a large
room... but it's powerful enough to loosen nails and split the
tongues.

That's also why the finish floor should be acclimatized in the same
room, or at least the same level of the house, where it will be laid.
