Hi Don,
Sorry, but that doesn't logically follow. Sure dry wood in damper air will 
absorb moisture and retain it until the air MC gets below that of the wood, 
and wet wood in dry air will release moisture to the air - which will 
retain it until... There's no indication in the above as to which will be 
faster - MC differences being equal. Air's hygroscopic too.
