As A Note I recall a discussion long ago that vacuum does not speed up water
diffusion.

Does anyone recall? The rate of diffusion was more dependent on the
concentration difference and temperature.

You might want to check out this paper:
Characteristic Times of Moisture Diffusion and Bake-out Conditions for
Plastic Encapsulated Parts written by Alexander Teverovsky QSS Group,
Inc./Goddard Operations [log in to unmask]

I have emailed you a copy.  Of note is that the key temperature for any bake
out under vacuum is 58C.
